Monitoring down a far-flung workforce for a 40-year reunion isn’t straightforward. However the individuals who labored on Home windows 1.0 bought some assist from their youthful selves: a mischievous Easter egg they hid way back within the software program that might turn out to be the inspiration of the world’s dominant PC platform.
Again within the mid-Eighties, earlier than the product launched, they secretly inserted credit within the code, itemizing their names, to be revealed by means of a particular mixture of keystrokes.
Because the story goes, Invoice Gates inadvertently discovered the record by slamming his fists on the keyboard in frustration over the system’s sluggishness, a discovery that solely made issues worse. The repair: make the sequence extra obscure. It labored. The credit went unnoticed by the general public till 2022, when a researcher who was reverse-engineering outdated Home windows binaries discovered them.
So when members of the Home windows 1.0 workforce determined to carry a fortieth anniversary reunion this yr, that roster grew to become their place to begin. It was a time capsule that doubled as a visitor record.
A core group from that unique Home windows workforce reunited over dinner at Steve Ballmer’s workplaces in Bellevue on Tuesday night — buying and selling recollections, correcting the historic document, and marveling at what they achieved again then underneath almost inconceivable circumstances.
“Right this moment, builders have all these instruments, drag and drop,” stated Rao Remala, an early Home windows developer, including that he would problem anybody immediately to construct a functioning PC working atmosphere underneath the 64K phase limits and different technical constraints of the period.
“Have you ever tried it in ChatGPT?” Ballmer joked from throughout the room.
This yr has been full of commemorative milestones for the tech large, from Microsoft’s fiftieth to Excel’s fortieth to the thirtieth anniversary of the corporate’s web pivot. However this one is completely different. It’s a glimpse into certainly one of Microsoft’s scrappiest tasks, from a second in its historical past when key sources — together with finances and computing energy — have been way more scarce.
Microsoft’s landmark platform
Home windows 1.0, which shipped on a set of 5.25-inch floppy disks, was technically thought of an working atmosphere, not an working system, as a result of it ran on MS-DOS 2.0.
Microsoft introduced that it was growing Home windows in November 1983. The discharge was delayed because the workforce labored by means of management turnover, technical challenges, and user-interface debates (i.e., tiled vs. overlapping home windows), giving rise to business accusations of peddling “vaporware.”
Home windows 1.0 lastly debuted on Nov. 20, 1985.

By the point Home windows launched, Apple’s Macintosh had set the usual with its elegant interface (no less than by Eighties requirements), and different DOS-based options have been additionally in the marketplace. Critics favored the Mac’s polish, however Microsoft wager on broad PC compatibility, and that strategy in the end paid off.
Microsoft would later get sidetracked briefly by its ill-fated OS/2 partnership with IBM, earlier than Home windows 3.1 grew to become a breakout hit and Home windows 95 set the worldwide normal.
However none of it might have been potential with out Home windows 1.0. The extraordinary, multi-year challenge was the inspiration for the platform that in the end turned Microsoft into one of many world’s most respected corporations, launching careers that might reshape the tech business.
For Ballmer, who was tapped to get Home windows 1.0 throughout the end line lengthy earlier than he grew to become Microsoft’s CEO, the 40-year reunion stirred up outdated recollections and feelings.
“Of all of the issues I labored on at Microsoft, in a means, I’ve essentially the most delight about this challenge,” he informed the group, explaining that he actually felt a part of the workforce.
Figuring issues out on the fly
Because the night time went on, the tales got here out, a few of them for the primary time.
Figuring out of Microsoft’s Bellevue workplaces, earlier than the corporate moved to Redmond, the workforce was largely of their 20s and even their teenagers in some circumstances. Ballmer, in his late 20s on the time, was one of many older folks within the workplace. That helps to elucidate the tradition on the time.
“Work and social life — there was no distinction. All of it kind of blended collectively,” stated Scott Ludwig, who labored on the Home windows 1.0 window supervisor, the core system that dealt with home windows, enter, occasions, menus, and dialog containers.
In lots of circumstances again then, they have been figuring issues out on the fly. For instance, when Lin Shaw began in August 1984, months earlier than the unique ship date, not a single printer driver existed. She constructed the banding structure — a means of imaging one strip of a web page at a time to work inside reminiscence constraints — that might final by means of Home windows 95.
She routinely stayed up all night time and thought of it the perfect job on this planet. “It was identical to school,” she informed the group in the course of the reunion dinner, “besides I bought paid rather well.”

Gates bought concerned, at instances, right down to the smallest particulars. Mark Taylor, who wrote the calculator and different early Home windows apps, recalled Gates asking him to take away a timer delay within the Reversi recreation — to not make it quicker, however to make Home windows look quicker. Years later, chips bought so quick that the transfer flashed by too rapidly to see, turning the repair right into a bug.
Joe King, who labored on the Home windows Management Panel, had an workplace throughout the corridor from Ballmer with remarkably skinny partitions. He watched a parade of individuals come for his or her “SteveB assembly.” The sample was all the time the identical: quiet dialog at first, then Ballmer would begin pacing, getting louder, gesturing emphatically, and reaching a crescendo earlier than it was over.
“The door would open, a man would sheepishly stroll out, and Steve would greet the following particular person with full vitality and enthusiasm,” King recalled. “I might see that each one day lengthy.”
Tandy Trower reminisced about becoming a member of the workforce in 1985 regardless of being warned that it was a lifeless finish by one other product supervisor, Rob Glaser, later of RealNetworks fame.
“I got here to Microsoft with this imaginative and prescient of bringing software program to the folks,” Trower stated, explaining that Ballmer pitched the Home windows challenge to him as a means of conducting that objective.
He took the job, solely to find the pinnacle improvement supervisor was already gone. Ballmer provided reassurances that the product was “just about finished.” It wasn’t.
When Trower steered adjustments — overlapping home windows, proportional fonts — he bought the identical response: “You wish to ship this yr?” The reply was sure. Trower ended up engaged on Home windows by means of Home windows 95, a part of a Microsoft profession that in the end spanned 28 years.
Marlin Eller, a programmer and musician, was fascinated by constructing a music notation editor. On the finish of his first yr, Gates requested what he wished to work on. Eller pitched his concept. Gates engaged enthusiastically, then requested: “How huge is the market?” Eller realized it was very small.
Gates had one other concept. For music notation, Eller would wish to construct a graphics package deal — strains, ovals, curves, and many others. An working system wanted that foundational expertise to help spreadsheets and charts. And that’s how Eller ended up engaged on Home windows.
“The factor the world doesn’t know,” Eller joked earlier than the dinner, “is that Home windows was written so I might do music notation. All these different folks have been working for me.”
Pulling pranks and checking details
After which there have been the pranks. A month or two earlier than Home windows 1.0 shipped, for instance, developer Mark Cliggett determined to have some enjoyable. He wrote a program that steadily turned off bits on a pc display, and put in it on Ballmer’s machine when he wasn’t there.
“A number of dangerous choices proper there,” Cliggett acknowledged: placing malware on a colleague’s pc, giving it to the longer term CEO, and lacking the irony given the safety challenges that might eat the business years later. Marlin Eller wasted an hour debugging the issue earlier than realizing what had occurred. Ballmer, to his credit score, didn’t maintain a grudge.
GeekWire was invited to cowl the Home windows 1.0 reunion and doc all this historical past. To arrange, I pulled collectively a 16-page report utilizing Google’s NotebookLM to mine for details about Home windows 1.0 in a wide range of historic paperwork, books, and articles.
After I discussed this to Ballmer, he steered I open the night by studying some colourful anecdotes from the analysis. It became an impromptu fact-checking train.
Did Ballmer actually name a gathering at 9 a.m. on Easter Sunday 1985 and take down the names of anybody who didn’t present? Sure, he referred to as the assembly. No, he didn’t take names. “I wouldn’t name it precisely a loyalty check,” Ballmer defined, saying it was extra about setting a tone.
Did the workforce actually blow off steam by making bombs and rockets with sugar and saltpeter, drawing police to the constructing when a safety guard smelled explosives? Truly, that occurred when making a later Home windows model, in line with somebody who was there. The safety guard joined them to explode visitors cones within the parking storage. The police got here later, after they have been hiding within the library. (The small print are slightly fuzzy, however you get the concept.)
And eventually, turning to a canonical story in regards to the Home windows 1.0 challenge: was the pivotal 1983 Comdex demo actually only a videotape flashing graphics on the display — basic smoke and mirrors to freeze the market? No. “This was actual code,” Remala insisted.
“It was slightly extra smoky than not,” Ballmer added, “nevertheless it was all actual code.”
Some notable former members of the Home windows 1.0 workforce have been lacking from the reunion, together with the famously hard-to-reach Gabe Newell, who went on to co-found Valve and construct Steam into the dominant PC gaming platform.
Scott McGregor, the lead improvement supervisor recruited from Xerox PARC, left earlier than Home windows 1.0 shipped. McGregor later co-authored the X11 windowing system at DEC and served as CEO of Broadcom.
Different members of the Home windows 1.0 workforce went on to remarkably various careers.
For instance, person interface developer Neil Konzen labored at Ferrari in Italy and pioneered Method One telemetry. Ed Mills, who labored on fonts, runs a motion remedy follow in Bellevue and is concerned in a nonprofit that operates a roller-skating rink in Issaquah.
Cliggett grew to become a long-distance working coach. Eller (who went on to co-author the e book Barbarians Led by Invoice Gates) teaches pc science. Trower based a robotics firm and continues to work within the subject. Taylor is a Seattle public college instructor.
King nonetheless introduces himself within the Seattle tech scene by saying he goes again to Home windows 1.0 — typically prompting the response: “There was a 1.0?” Sure, there certain was.
For Ballmer, the Home windows 1.0 expertise led to a administration approach he nonetheless makes use of immediately. On his first day as improvement supervisor, he repeated to the workforce what he’d been informed was the schedule for various facets of the challenge. He heard laughter in response.
He now calls this the “snicker check” — repeat again what you’ve heard from a challenge’s leaders, and see how the room reacts. In the event that they chuckle, you understand you’re not getting the true story.
However the true legacy of Home windows is way larger, he informed the group this week. If it had shipped two or three years later, Home windows wouldn’t have been a related product, he stated. The important thing, he defined, was determining the right way to ship “sufficient of the correct stuff on the proper time.”
“You probably did, and it’s nothing in need of wonderful,” Ballmer stated. “It did change the world.”
