“If 32-bit OS/2 had launched as planned, Windows 3 would have been the last version before it was absorbed into OS/2 and disappeared.” I don’t think so - Micro

“If 32-bit OS/2 had launched as planned, Windows 3 would have been the last version before it was absorbed into OS/2 and disappeared.” I don’t think so - Microsoft would have preferred having 100% control instead of sharing OS/2 with IBM. Windows 3.0 was the technical foundation that allowed things to go the way they went, and its technical capabilities were known, even if it needed time to prove itself in the market. Microsoft would likely have pushed Windows a lot harder than OS/2 even if they had both been concurrently available. OS/2 was my primary OS for a few years and it was truly awesome - we did things like running a 3-node BBS out of a single 486 with 12 MB RAM and one could format a floppy disk while the system remained responsive (try that with Windows). Fun times.

The only way this would have happened is if Dave Cutler had never left DEC. Microsoft had already been the biggest commercial UNIX vendor with Xenix, and obtaining the architect of the VMS kernel gave them a brain trust that IBM could not match. I don't think that Dave Cutler would have been happy as one of several contributors to OS/2 as it slowly grew out of the 286. I think it was dead the moment he walked in the door.

  Exactly this, and we should not valorize OS/2 as an operating system foundation. The kernel in NT is far superior. The "alternate timeline" I'd be more interested in is one where NT had propagated as a more open solution with either open source or more reasonable licensing costs, with a better more VMS and/or Unix-like CLI driven user space and multiple vendors offering systems somehow.

    On the one hand, I have no idea why NT chose CMD.EXE as their command shell instead of pdksh; most would ascribe this to the influence of OS/2. NT was built with a POSIX interface, and Korn would have been a much better fit; one objection might be that NT forks processes very slowly, which is a major aspect of Korn. On the other hand, I don't believe Dave Cutler would have ever allowed /usr/src to ship with the source code to the kernel.

      Ill take a stab at that. command.com scripts were very similar to cmd.exe scripts. That was important to get people to actually use the thing. You can see the same thing today with powershell. PS is in many ways better. Except it does not run the old scripts very well. Even something simple like 'dir /s' does not work in powershell you have to do it the powershell way. If they had moved to sh style command eventually they would have been fine. But... their existing base would have been very unhappy with the results in the short term.
      - chasil 3y ago
        At the same time, Xenix had a huge influence on Microsoft. I can't believe that anyone with taste would want CMD.EXE, and the criticism is deep. https://blog.nullspace.io/batch.html https://blog.nullspace.io/batch.html
        sumtechguy 3y ago
        Oh no doubt it is a rubish language to program in. The thing is their existing base had a set of scripts that already worked. These are not 5 line scripts either. One place I worked at the thing was probably 20k lines of batch script. To hand them a new shell is akin to saying 'throw everything you did out and redo it'. Those scripts were probably home grown by people who had other things to do (you work with what you have). Or by expensive consultants. They 'must work' or 'why am I upgrading to this?' It is not necessarily hard to do. It just an extra expense most businesses are going to skip if they can.

        Some reasons why CMD.EXE is so bad: (1) COMMAND.COM cut a lot of corners, in significant part due to being written in assembly and designed to run on machines with very low memory (DOS 1.0 would run on machines with only 32KB of RAM) (2) Backward compatibility meant a lot of the questionable decisions in (1) had to be maintained (3) At some point Microsoft stopped investing in it, and didn't do anything further to add new features or file off more rough edges I think (1) and (2) were kind of inevitable, but (3) is a decision Microsoft has made much more recently I wish they'd open-source CMD.EXE and start accepting PRs for it – I think some of the worst things about it (e.g. the "Terminate batch job (Y/N)?" prompt which is impossible to turn off without patching the executable) would get fixed. But I doubt they'll do that because they just want people to focus on PowerShell instead–and before PowerShell, it was the same thing for VBScript

    Microsoft could still open source some or all of the NT kernel and try to compete for mindset. It's still incredible how much work they put into porting the NT Kernel for some embedded scenarios (you can run it on a Raspberry Pi or things smaller than it) in the Windows 10 lifetime but couldn't seem to understand why more people weren't licensing it more when Linux is cheap as free for embedding. Even when Microsoft went to "free licenses" (still with too many caveats such as type and size of screen attached) the open source appeal was hard to get past. I'm still somewhat surprised with all of Microsoft's cloud focus and how much of Windows is getting open sourced that the NT Kernel itself hasn't been a priority to win back embedded applications that Microsoft has lost to Linux especially. I certainly understand the massive sunk costs in the NT Kernel that some accountants would see it as too much very expensive proprietary R&D, but it's still interesting to imagine what would happen if Microsoft got over that hump, even if they kept the Win32 userspace and most of the rest of Windows proprietary.
    - floating-io 3y ago
      It may be that they can't release it open source. How much of other peoples' proprietary code is in that kernel? To be clear, I'm not talking illegal theft or anything of the sort -- but it's quite possible that they've licensed things over the years (code, patents, ...) and thus cannot open source it. Not saying this is or isn't true, just something to consider when trying to figure out the why of things.
      - chasil 3y ago
        Actually, a lot of the kernel code has leaked in the past, so this question can be independently answered. I know that there were a few leaks at different times. Some of it appears to be here: https://github.com/0x5bfa/NT5.1 https://github.com/0x5bfa/NT5.1
      - WorldMaker 3y ago
        They did finally kick their fork of Adobe's Type 1 Font Manager out of the Kernel in recent years (somewhere in the middle of Windows 10 as I recall), so that's definitely a complication to expect.

Things happened the way they did because DEC cancelled Prism and Mica and he decamped to MS. But the point here is that, 3 years before NT, MS had a very capable 386 OS and this shows it, complete with screenshots.

We're not talking about that alternate history here. What the article is about is that MS had a complete working 386 OS in 1990... but chose to kill it, and it would be another 3 years before its own in-house version was ready, and a decade after that before that in-house 32-bit OS finally replaced DOS-based Windows.
  - chasil 3y ago
    From Showstopper! The Breakneck Race to Create Windows NT and the Next Generation at Microsoft by Zachary, we learn that Microsoft hired Cutler in October of 1988. By this time, Microsoft had already maintained a 32-bit kernel with a flat memory model as Xenix. They disposed of it because AT&T was entering the commercial UNIX market and Microsoft would be at a distinct disadvantage. This means that Cutler had been expounding on his grand kernel plans for two years prior to the 32-bit OS/2 from 1990, and staff at Microsoft could very well grasp the significance. Chapter 4 of Zachary, Blind Alley, claims that the NT development kernel booted on an i860 PC in July of 1989. This being the case, the knives must have been out for OS/2 for some time. https://en.wikipedia.org/wiki/Dave_Cutler https://en.wikipedia.org/wiki/Dave_Cutler

      From the start, there were 3 planned editions of OS/2. 1.x - 16-bit, for the 80286 2.x - 32-bit, for the 80386 3.x - 32-bit, portable and CPU-independent, aimed at RISC chips. MS also had a multitasking DOS 4, never fully commercially released. https://en.wikipedia.org/wiki/MS-DOS_4.0_(multitasking) https://en.wikipedia.org/wiki/MS-DOS_4.0_(multitasking) http://www.os2museum.com/wp/multitasking-ms-dos-4-0-lives/ http://www.os2museum.com/wp/multitasking-ms-dos-4-0-lives/ What became NT started out as OS/2 3.

100% control/ownership was "the Microsoft way", but perhaps there's an alternate universe where they did jointly launch OS/2 due to business needs, with Microsoft intending to claw back control. Would have been interesting to see them fight over ownership! I ran OS/2 Warp for a couple years as my daily driver and agree, it was a fantastic OS. Stable as heck, preemptive multitasking, just a solid workhorse. I would say Windows got "good enough" with Windows 2000, and pretty decent with the release of XPSP3. Many years later....
