Come August of 1984, Microsoft Windows had missed its originally announced release date by four months and was still nowhere near ready to go. That month, IBM released the PC/AT, a new model of their personal computer based around the more powerful Intel 80286 processor. Amidst the hoopla over that event, they invited Microsoft and other prominent industry players to a sneak preview of something called TopView, and Bill Gates got an answer at last to the fraught question of why IBM had been so uninterested in his own company’s Windows operating environment.

TopView had much in common with Windows and the many other attempts around the industry, whether already on the market or still in the works, to build a more flexible and user-friendly operating environment upon the foundation of MS-DOS. Like Windows and so many of its peers, it would offer multitasking, along with a system of device drivers to isolate applications from the underlying hardware and a toolkit for application developers that would allow them to craft software with a consistent look and feel. Yet one difference made TopView stand out from the pack — and not necessarily in a good way. While it did allow the use of a mouse and offered windows of a sort, it ran in text rather than graphics mode. The end result was a long, long way from the Macintosh-inspired ideal of intuitiveness and attractiveness which Microsoft dreamed of reaching with their own GUI environment.

TopView at the interface level resembled something IBM might have produced for the mainframe market back in the day more than it did Windows and the other microcomputer GUI environments that were its ostensible competitors. Like IBM’s mainframe system software, it was a little stodgy, not terribly pretty, and not notably forgiving toward users who hadn’t done their homework, yet had a lot to offer underneath the hood to anyone who could accept its way of doing business. It was a tool that seemed designed to court power users and office IT administrators, even as its competitors advertised their ease of use to executives and secretaries.

Within its paradigm, though, TopView was a more impressive product than it’s generally given credit for being even today. It sported, for example, true preemptive multitasking ^[1]This is perhaps a good point to introduce a quick primer on multitasking techniques to those of you who may not be familiar with its vagaries. The first thing to understand is that multitasking during this period was fundamentally an illusion. The CPUs in the computers of this era were actually only capable of doing one task at a time. Multitasking was the art of switching the CPU’s attention between tasks quickly enough that several things seemed to be happening at once — that several applications seemed to be running at once. There are two basic approaches to creating this illusionary but hugely useful form of multitasking.

Cooperative multitasking — found in systems like the Apple Lisa, the Apple Macintosh between 1987’s System 5 and the introduction of OS X in 2001, and early versions of Microsoft Windows — is so named because it relies on the cooperation of the applications themselves. A well-behaved, well-programmed application is expected to periodically relinquish its control of the computer voluntarily to the operating system, which can then see if any of its own tasks need to be completed or any other applications have something to do. A cooperative-multitasking operating system is easier to program and less resource-intensive than the alternative, but its most important drawback is made clear to the user as soon as she tries to use an application that isn’t terribly well-behaved or well-programmed. In particular, an application that goes into an infinite loop of some sort — a very common sort of bug — will lock up the whole computer, bringing the whole operating system down with it.

Preemptive multitasking — found in the Commodore Amiga, Mac OS X, Unix and Linux, and later versions of Microsoft Windows — is so named because it gives the operating system the authority to wrest control from — to preempt — individual applications. Thus even a looping program can only slow down the system as a whole, not kill it entirely. For this reason, it’s by far the more desirable approach to multitasking, but also the more complicated to implement. months before the arrival of the Commodore Amiga, the first personal computer to ship with such a feature right out of the box. Even ill-behaved vanilla MS-DOS applications could be coerced into multitasking under TopView. Indeed, while IBM hoped, like everyone else making extended operating environments, to tempt third-party programmers into making native applications just for them, they were willing to go to heroic lengths to get existing MS-DOS applications working inside TopView in the meantime. They provided special specifications files — known as “Program Information Files,” or PIFs — for virtually all popular MS-DOS software. These told TopView exactly how and when their subjects would try to access the computer’s hardware, whereupon TopView would step in to process those calls itself, transparently to the ill-behaved application. It was an admittedly brittle solution to a problem which seemed to have no unadulteratedly good ones; it required IBM to research the technical underpinnings of every major new piece of MS-DOS software that entered the market in order to keep up with an endless game of whack-a-mole that was exhausting just to think about. Still, it was presumably better than punting on the whole problem of MS-DOS compatibility, as Visi On had done. Whatever else one could say about IBM’s approach to extending MS-DOS, they thus had apparently learned at least a little something from the travails of their competitors. Even the decision to run in character mode sounds far more defensible when you consider that up to two-thirds of MS-DOS computers at the time of TopView’s release were equipped only with a monochrome screen capable of no other mode.

Unfortunately, TopView failed to overcome many of the other issues that dogged its competitors. Having been so self-consciously paired with the pricey PC/AT, it was still a bit out in front of the sweet spot of hardware requirements, requiring a 512 K machine to do much of anything at all. And it was still dogged by the 640 K barrier, that most troublesome of all aspects of MS-DOS’s primitiveness. With hacks to get around the barrier still in their relative infancy, TopView didn’t even try to support more memory, and this inevitably limited the appeal of its multitasking capability. With applications continuing to grow in complexity and continuing to gobble up ever more memory, it wouldn’t be long before 640 K wouldn’t be enough to run even two pieces of heavyweight business software at the same time, especially after one had factored in the overhead of the operating environment itself.

A Quick Tour of TopView

---

TopView shipped in March of 1985 — later than planned, but nowhere near as late as Microsoft Windows, which was now almost a full year behind schedule. It met a fractious reception. Some pundits called it the most important product to come out of IBM since the release of the original IBM PC, while others dismissed it as a bloated white elephant that hadn’t a prayer of winning mainstream acceptance — not even with the IBM logo on its box and a surprisingly cheap suggested list price of just $149. For many IBM watchers — not least those watching with concern inside Microsoft — TopView was most interesting not so much as a piece of technology as a sign of IBM’s strategic direction. “TopView is the subject of fevered whispers throughout the computer industry not because of what it does but because of what it means,” wrote PC Magazine. It had “sent shivers through the PC universe and generated watchfulness” and “possibly even paranoia. Many experts think, and some fear, that TopView is the first step in IBM’s lowering of the skirt over the PC — the beginning of a closed, proprietary operating system.”

Many did indeed see TopView as a sign that IBM was hoping to return to the old System/360 model of computing, seizing complete control of the personal-computing market by cutting Microsoft out of the system-software side. According to this point of view, the MS-DOS compatibility IBM had bent over backward to build into TopView needed last only as long as it took third-party developers to write native TopView applications. Once a critical mass of same had been built up, it shouldn’t be that difficult to decouple TopView from MS-DOS entirely, turning it into a complete, self-standing operating system in its own right. For Bill Gates, this was a true nightmare scenario, one that could mean the end of his business.

But such worries about a TopView-dominated future, to whatever extent he had them, proved unfounded. A power-user product with mostly hacker appeal in a market that revolved around the business user just trying to get her work done, TopView quickly fizzled into irrelevance, providing in the process an early warning sign to IBM, should they choose to heed it, that their omnipotence in the microcomputer market wasn’t as complete as it had been for so long in the mainframe market. IBM, a company that didn’t abandon products easily, wouldn’t officially discontinue TopView until 1988. By that time, though, the most common reaction to the news would be either “Geez, that old thing was still around?” or, more likely, “What’s TopView?”

Of course, all of this was the best possible news from Microsoft’s perspective. IBM still needed the MS-DOS they provided as much as ever — and, whatever else happened, TopView wasn’t going to be the as-yet-unreleased Windows’s undoing.

In the meantime, Bill Gates had Windows itself to worry about, and that was becoming more than enough to contend with. Beginning in February of 1984, when the planned Windows release date was given a modest push from April to May of that year, Microsoft announced delay after delay after delay. The constant postponements made the project an industry laughingstock. It became the most prominent target for a derisive new buzzword that had been coined by a software developer named Ann Winblad in 1983: “vaporware.”

Inside Microsoft, Windows’s reputation was little better. As 1984 wore on, the project seemed to be regressing rather than progressing, becoming a more and more ramshackle affair that ran more and more poorly. Microsoft’s own application developers kicked and screamed when asked to consider writing something for Windows; they all wanted to write for the sexy Macintosh.

Neil Konzen, a Microsoft programmer who had been working with the Macintosh since almost two years before that machine’s release, was asked to take a hard look at the state of Windows in mid-1984. He told Bill Gates that it was “a piece of crap,” “a total disaster.” Partially in response to that verdict, Gates pushed through a corporate reorganization, placing Steve Ballmer, his most trusted lieutenant, in charge of system software and thus of Windows. He reportedly told Ballmer to get Windows done or else find himself a job at another company. And in corporate America, of course, shit rolls downhill; Ballmer started burning through Windows project managers at a prodigious pace. The project acquired a reputation inside Microsoft as an assignment to be avoided at all costs, a place where promising careers went to die. Observers inside and outside the project’s orbit were all left with the same question: just what the hell was preventing all these smart people from just getting Windows done?

The fact was that Windows was by far the biggest thing Microsoft had ever attempted from the standpoint of software engineering, and it exposed the limitations of the development methodology that had gotten them this far. Ever since the days when Gates himself had cranked out their very first product, a version of BASIC to be distributed on paper tape for the Altair kit computer, Microsoft had functioned as a nested set of cults of personality, each project driven by if not belonging solely to a single smart hacker who called all the shots. For some time now, the cracks in this edifice had been peeking through; even when working on the original IBM PC, Gates was reportedly shocked and nonplussed at the more structured approach to project management that was the norm at IBM, a company that had already brought to fruition some of the most ambitious projects in the history of the computer industry. And IBM’s project managers felt the same way upon encountering Microsoft. “They were just a bunch of nerds, just kids,” remembers one. “They had no test suites, nothing.” Or, as another puts it:

They had a model where they just totally forgot about being efficient. That blew our minds. There we were watching all of these software tools that were supposed to work together being built by totally independent units, and nobody was talking to each other. They didn’t use any of each other’s code and they didn’t share anything.

With Windows, the freelancing approach to software development finally revealed itself to be clearly, undeniably untenable. Scott MacGregor, the recent arrival from Xerox who was Windows’s chief technical architect in 1984, remembers his frustration with this hugely successful young company — one on whose products many of the Fortune 500 elite of the business world were now dependent — that persisted in making important technical decisions on the basis of its employees’ individual whims:

I don’t think Bill understood the magnitude of doing a project such as Windows. All the projects Bill had ever worked on could be done in a week or a weekend by one or two different people. That’s a very different kind of project than one which takes multiple people more than a year to do.

I don’t think of Bill as having a lot of formal management skills, not in those days. He was kind of weak on managing people, so there was a certain kind of person who would do well in the environment. There were a lot of people at that time with no people skills whatsoever, people who were absolutely incompetent at managing people. It was the Peter Principle: very successful technical people would get promoted to management roles. You’d get thirty people reporting to one guy who was not on speaking terms with the rest of the group, which is inconceivable.

One has to suspect that MacGregor had one particular bête noir in mind when talking about his “certain kind of person.” In the eyes of MacGregor and many others inside Microsoft, Steve Ballmer combined most of Bill Gates’s bad qualities with none of his good ones. Like Gates, he had a management style that often relied on browbeating, but he lacked the technical chops to back it up. He was a yes man in a culture that didn’t suffer fools gladly, a would-be motivational speaker who too often failed to motivate, the kind of fellow who constantly talked at you rather with you. One telling anecdote has him visiting the beleaguered Windows team to deliver the sort of pep talk one might give to a football team at halftime, complete with shouts and fist pumps. He was greeted by… laughter. “You don’t believe in this?” Ballmer asked, more than a little taken aback. The team just stood there uncomfortably, uncertain how to respond to a man that MacGregor and many of the rest of them considered almost a buffoon, a “non-tech cheerleader.”

And yet MacGregor had problems of his own in herding the programmers who were expected to implement his grand technical vision. Many of them saw said vision as an overly slavish imitation of the Xerox Star office system, whose windowing system he had previously designed. He seemed willfully determined to ignore the further GUI innovations of the Macintosh, a machine with which much of Microsoft — not least among them Bill Gates — were deeply enamored. The most irritating aspect of his stubbornness was his insistence that Windows should employ only “tiled windows” that were always stretched the horizontal length of the screen and couldn’t overlay one another or be dragged about freely in the way of their equivalents on the Macintosh.

All of this created a great deal of discord inside the project, especially given that much of MacGregor’s own code allegedly didn’t work all that well. Eventually Gates and Ballmer brought in Neil Konzen to rework much of MacGregor’s code, usurping much of his authority in the process. As Windows began to slip through MacGregor’s fingers, it began to resemble the Macintosh more and more; Konzen was so intimately familiar with Apple’s dream machine that Steve Jobs had once personally tried to recruit him. According to Bob Belleville, another programmer on the Windows team, Konzen gave to Windows “the same internal structure” as the Macintosh operating system; “in fact, some of the same errors were carried across.” Unfortunately, the tiled-windows scheme was judged to be too deeply embedded by this point to change.

In October of 1984, Microsoft announced that Windows wouldn’t ship until June of 1985. Gates sent Ballmer on an “apology tour” of the technology press, prostrating himself before journalist after journalist. It didn’t seem to help much; the press continued to pile on with glee. Stewart Alsop II, the well-respected editor of InfoWorld magazine, wrote that “buyers probably believe the new delivery date for Windows with the same fervor that they believe in Santa Claus.” Then, he got downright nasty: “If you’ve got something to sell, deliver. Otherwise, see to the business of creating the product instead of hawking vaporware.”

If the technology press was annoyed with Microsoft’s constant delays and prevarications, the third parties who had decided or been pressured into supporting Windows were getting even more impatient. One by one, the clone makers who had agreed to ship Windows with their machines backed out of their deals. Third-party software developers, meanwhile, kept getting different versions of the same letter from Microsoft: “We’ve taken the wrong approach, so everything you’ve done you need to trash and start over.” They too started dropping one by one off the Windows bandwagon. The most painful defection of all was that of Lotus, who now reneged on their promise of a Windows version of Lotus 1-2-3. The latter was the most ubiquitous single software product in corporate America, excepting only MS-DOS, and Microsoft had believed that the Windows Lotus 1-2-3 would almost guarantee their new GUI environment’s success. The question now must be whether the lack of same would have the opposite effect.

In January of 1985, Steve Ballmer brought in Microsoft’s fifth Windows project manager: Tandy Trower, a three-year veteran with the company who had recently been managing Microsoft BASIC. Trower was keenly aware of Bill Gates’s displeasure at recent inroads being made into Microsoft’s traditional BASIC-using demographic by a new product called Turbo Pascal, from a new industry player called Borland. The Windows project’s reputation inside Microsoft was such that he initially assumed he was being set up to fail, thereby giving Gates an excuse to fire him. “Nobody wanted to touch Windows,” remembers Trower. “It was like the death project.”

Trower came in just as Scott MacGregor, the Xerox golden boy who had arrived amidst such high expectations a year and a half before, was leaving amidst the ongoing discord and frustration. Ballmer elected to replace MacGregor with… himself as Windows’s chief technical architect. Not only was he eminently unqualified for such a role, but he thus placed Trower in the awkward position of having the same person as both boss and underling.

As it happened, though, there wasn’t a lot of need for new technical architecting. In that respect at least, Trower’s brief was simple. There were to be no new technical or philosophical directions explored, no more debates over the merits of tiled versus overlapping windows or any of the rest. The decisions that had already been made would remain made, for better or for worse. Trower was just to get ‘er done, thereby stemming the deluge of mocking press and keeping Ballmer from having to go on any more humiliating apology tours. He did an admirable job, all things considered, of bringing some sort of coherent project-management methodology to a group of people who desperately needed one.

What could get all too easily lost amidst all the mockery and all very real faults with the Windows project as a functioning business unit was the sheer difficulty of the task of building a GUI environment without abandoning the legacy of MS-DOS. Unlike Apple, Microsoft didn’t enjoy the luxury of starting with a clean slate; they had to keep one foot in the past as well as one in the future. Nor did they enjoy their competitor’s advantage of controlling the hardware on which their GUI environment must run. The open architecture of the IBM PC, combined with a market for clones that was by now absolutely exploding, meant that Microsoft was forced to contend with a crazy quilt of different hardware configurations. All those different video cards, printers, and memory configurations that could go into an MS-DOS machine required Microsoft to provide drivers for them, while all of the popular existing MS-DOS applications had to at the very least be launchable from Windows. Apple, by contrast, had been able to build the GUI environment of their dreams with no need to compromise with what had come before, and had released exactly two Macintosh models to date — models with an architecture so closed that opening their cases required a special screwdriver only available to Authorized Apple Service Providers.

In the face of all the challenges, some thirty programmers under Trower “sweated blood trying to get this thing done,” as one of them later put it. It soon became clear that they weren’t going to make the June 1985 deadline (thus presumably disappointing those among Stewart Alsop’s readers who still believed in Santa Claus). Yet they did manage to move forward in far more orderly fashion than had been seen during all of the previous year. Microsoft was able to bring to the Comdex trade show in May of 1985 a version of Windows which looked far more complete and polished than anything they had shown before, and on June 28, 1985, a  feature-complete “Preview Edition” was sent to many of the outside developers who Microsoft hoped would write applications for the new environment. But the official first commercial release of Windows, known as Windows 1.01, didn’t ship until November of 1985, timed to coincide with that fall’s Comdex show.

In marked contrast to the inescapable presence Windows had been at its first Comdex of two years before, the premiere of an actual shipping version of Windows that November was a strangely subdued affair. But then, the spirit of the times as well was now radically different. In the view of many pundits, the bloom was rather off the rose for GUIs in general. Certainly the GUI-mania of the Fall 1983 Comdex and Apple’s “1984” advertisement now seemed like the distant past. IBM’s pseudo-GUI TopView had already failed, as had Visi On, while the various other GUI products on offer for MS-DOS machines were at best struggling for marketplace acceptance. Even the Macintosh had fallen on hard times, such that many were questioning its very survival. Steve Jobs, the GUI’s foremost evangelist, had been ignominiously booted from Apple the previous summer — rendered, as the conventional wisdom would have it, a has-been at age thirty. Was the GUI itself doomed to suffer the same fate? What, asked the conventional-wisdom spouters, was really so bad about MS-DOS’s blinking command prompt? It was good enough to let corporate America get work done, and that was the important thing. Surely it wouldn’t be Windows, an industry laughingstock for the better part of two years now, that turned all this GUI hostility back in the market’s face. Windows was launching into a headwind fit to sink the Queen Mary.

It was a Microsoft public-relations specialist named Pam Edstrom who devised the perfect way of subverting the skepticism and even ridicule that was bound to accompany the belated launch of the computer industry’s most infamous example of vaporware to date. She did so by stealing a well-worn page from the playbook of media-savvy politicians and celebrities who have found themselves embroiled in controversy. How do you stop people making fun of you? Why, you beat them to the punch by making fun of yourself first.

Edstrom invited everybody who was anybody in technology to a “Microsoft Roast” that Comdex. The columnist John C. Dvorak became master of ceremonies, doing a credible job with a comedic monologue to open the affair. (Sample joke about the prematurely bald Ballmer: “When Windows was first announced, Ballmer still had hair!”) Gates and Ballmer themselves then took the stage, where Stewart Alsop presented them with an InfoWorld “Golden Vaporware Award.” The two main men of Microsoft then launched into a comedy routine of their own that was only occasionally cringe-worthy, playing on their established reputations as the software industry’s enfant terrible and his toothy-but-not-overly-bright guard dog. Gates said that Ballmer had wanted to cut features: “He came up with this idea that we could rename this thing Microsoft Window; we would have shipped that a long time ago.” Ballmer told how Gates had ordered him to “ship this thing before the snow falls, or you’ll end your career here doing Windows!”; the joke here was that in Seattle, where the two lived and worked, snow almost never falls. Come the finale, they sang the “The Impossible Dream” together as a giant shopping cart containing the first 500 boxed copies of Windows rolled onto the stage amidst billows of dry ice.

All told, it was a rare display of self-deprecating humanity and showmanship from two people not much known for either. From a PR perspective, it was about the best lemonade Microsoft could possibly have made out of a lemon of a situation. The press was charmed enough to start writing about Windows in more cautiously positive terms than they had in a long, long time. “The future of integration [can] be perceived through Windows,” wrote PC World. Meanwhile Jim Seymour, another respected pundit, wrote a column for the next issue of PC Week that perfectly parroted the message Microsoft was trying to get across:

I am a Windows fan, not because of what it is today but what it almost certainly will become. I think developers who don’t build Windows compatibility into new products and new releases of successful products are crazy. The secret of Windows in its present state is how much it offers program developers. They don’t have to write screen drivers [or] printer drivers; they can offer their customers a kind of two-bit concurrency and data exchange.

The most telling aspect of even the most sympathetic early reviews is their future orientation; they emphasize always what Windows will become, not what it is. Because what Windows actually was in November of 1985 was something highly problematic if not utterly superfluous.

The litany of problems began with that same old GUI bugaboo: performance. Two years before, Bill Gates had promised an environment that would run on any IBM PC or clone with at least 192 K of memory. Technically speaking, Microsoft had come very close to meeting that target: Windows 1.01 would run even on the original IBM PC from 1981, as long as it had at least 256 K of memory. It didn’t even absolutely require a hard drive. But running and running well — or, perhaps better put, running usably — were two very different matters. Windows could run on a floppy-based system, noted PC Magazine dryly, “in the same sense that you can bail a swimming pool dry with a teaspoon.” To have a system that wasn’t so excruciatingly slow as to outweigh any possible benefit it might deliver, you really needed a hard drive, 640 K or more of memory, and an 80286 processor like that found in the IBM PC/AT. Even on a hot-rod machine like this, Windows was far from snappy. “Most people will say that any screen refresh that can be watched takes too long,” wrote PC Magazine. “Very little happens too quickly to see in Windows.” One of Microsoft’s own Windows programmers would later offer a still more candid assessment: even at this late date, he would say, “Windows was a pig,” the result of a project that had passed through too many hands and had too many square chunks of code hammered into too many round holes.

Subjectively, Windows felt like it had been designed and programmed by a group of people who had read a whole lot about the Macintosh but never actually seen or used one. “I use a Macintosh enough to know what a mouse-based point-and-click interface should feel like,” wrote John C. Dvorak after the goodwill engendered by the Microsoft Roast had faded. “Go play with a Mac and you’ll see what I mean. Windows is clunky by comparison. Very clunky.” This reputation for endemic clunkiness — for being a Chrysler minivan pitted against Apple’s fine-tuned Porsche of a GUI — would continue to dog Windows for decades to come. In this first release, it was driven home most of all by the weird and unsatisfying system of “tiled” windows.

All of which was a shame because in certain ways Windows was actually far more technically ambitious than the contemporary Macintosh. It offered a cooperative-multitasking system that, if not quite the preemptive multitasking of TopView or the new Commodore Amiga, was more than the single-tasking Mac could boast. And it also offered a virtual-memory scheme which let the user run more applications than would fit inside 640 K. Additional RAM beyond the 640 K barrier or a hard drive, if either or both were extant, could be used as a swap space when the user tried to open more applications than there was room for in conventional memory. Windows would then automatically copy data back and forth between main memory and the swap space as needed in order to keep things running. The user was thus freed from having to constantly worry about her memory usage, as she did in TopView — although performance problems quickly started to rear their head if she went too crazy. In that circumstance, “the thrashing as Windows alternately loads one application and then the other brings the machine to its knees,” wrote PC Magazine, describing another trait destined to remain a Windows totem for years to come.

A Quick Tour of Windows 1.01

---

By the time Windows was ready, all of the clone makers whom Bill Gates had cajoled and threatened into shipping it with their computers had jumped off the bandwagon, telling him that it had simply taken him too long to deliver, and that the product which he had finally delivered was simply too slow on most hardware for them to foist it on their customers in good conscience. With that path to acceptance closed to them, Microsoft was forced to push Windows as a boxed add-on sold through retail channels, a first for them in the context of a piece of system software. In a measure of just how badly Gates wanted Windows to succeed, Microsoft elected to price it at only $99 — one-tenth of what VisiCorp had tried to ask for Visi On two years before — despite its huge development cost.

Unfortunately, the performance problems, the awkwardness of the tiled windows, and the almost complete lack of native Windows applications beyond those that shipped with the environment outweighed the low price; almost nobody bought the thing. Microsoft was trapped by the old chicken-or-the-egg conundrum that comes with the launch of any new computing platform — a problem that is solved only with difficulty in even the best circumstances. Buyers wanted to see Windows applications before they bought the operating environment, while software developers wanted to see a market full of eager buyers before they invested in the platform. The fact that Windows could run most vanilla MS-DOS applications with some degree or another of felicity only helped the software developers make the decision to stay away unless and until the market started screaming for Windows-native versions of their products. Thus, the MS-DOS compatibility Microsoft had built into Windows, which had been intended as a mere bridge to the Windows-native world of the future, proved something of a double-edged sword.

When you add up all of the hard realities, it comes as little surprise that Microsoft’s first GUI sparked a brief run of favorable press notices, a somewhat longer run of more skeptical commentary, and then disappeared without a trace. Already by the spring of 1986, it was a non-factor, appearing for all the world to be just one more gravestone in the GUI graveyard, likely to be remembered only as a pundit’s punch line. Bill Gates could comfort himself only with the fact that IBM’s own big system-software innovation had landed with a similar splat.

IBM and Microsoft had each tried to go it alone, had each tried to build something better upon the foundation of MS-DOS, and had each struck out swinging. What now? Perhaps the odd couple still needed one another, loath though either was to admit it. In fact, by that spring of 1986 a gradual rapprochement had already been underway for a year, despite deep misgivings from both parties. TopView and Windows 1 had both been a bust, but neither company had gotten where they were by giving up easily. If they pooled their forces once again, who knew what they might achieve. After all, it had worked out pretty well the first time around.
