Win your Ultimate Tech Bundle by entering Fasthosts’ Techie Test here: (competition is now closed).... There was once a piece of code, buried deep within Windows, designed to detect competitor operating systems, and upon finding them, CRASH... or at least, make the user feel like something was seriously wrong. This was Microsoft's attempt to truly kill Digital Research's DR-DOS, and although it worked, it wasn't long until the true nature of Microsoft's practices was uncovered.

The editors used to be included with the windows installation tools and it wasn't that hard to get windows through 2000 up and running on almost anything. Sometimes it was a long upgrade path but it was a lot of fun every time.

  • I remember some of this and I had my own tricks. DR. DOS 5 would only support windows in extended mode but setup did not use extended mode. It used standard mode. There was a simple remedy. Boot with an MS DOS 5 boot floppy, install Windows 3.1 and then reboot. Windows would not run in extended mode. I considered that stunt clear. Windows 3.1 would install normally under DR DOS 6.

  • This reminds me of the deliberate CSS bug that Microsoft planted on their web sites that would cause web sites to shift off-screen if a rival browser was detected. This was when CSS layouts just became a thing. So, browsers that supported CSS properly would end up not properly displaying Microsoft's web pages (or rather: properly displaying it, but in the way that Microsoft wanted, i.e. off-screen).

    SGresponseSGresponseMånad sedan
    • Yeah, I think DRDOS (and other products from companies like Quarterdeck) just made it easier. On plain MSDOS there was a lot of trial and error. In retrospect it's all stuff that should not have been necessary in the first place. We were running an OS on 386+ CPUs that was made to run on 8086 CPUs.

  • In some ways, I'm surprised that Windows survived at all. Early versions like this were so bloated and clunky that most people I knew were really unhappy with the performance and only used them because they preferred to have a GUI. Now, I see these shenanigans and wonder if this extra added code, and it being "spread out all over the place" is a big reason that those platforms were so slow and clunky. Have seriously considered switching to Linux as a daily driver many times and giving more and more serious consideration these days.

    TJEssaryTJEssaryMånad sedan
    • Indeed, monopolies have more far reaching effects than people realize. If you were really a PC power user back in the 90's, Windows 3.x was pretty much irrelevant. It was just a DOS shell. I switched to Linux in the mid 90's and never looked back. I was lucky and worked in IT so I was even able to us Linux as my workstation. Then I switched to OS X in the mid-late 00's. I never ran WIndows as my daily driver.

    wwazmanwwazmanMånad sedan
    • That value didn't really mean much in practical terms. That was is the 32bit theoretical limit of accessible memory. I don't think there was any PC at the time which could hold that much RAM, and even if there was, it would be ridiculously expensive. 4 megabytes was more realistic.

      YarnoshYarnoshMånad sedan
  • By having that code in the Windows 3.1 beta image, it provides proof of intent to damage the reputation of a up and coming software corporation. It seems like Microsoft in it's relative infancy was one large and expensive lawsuit away from destroying itself. What a curious risk for a company to take.

    Antony FirewalkAntony Firewalk2 månader sedan
    • It's difficult to say. Depends if you are just talking x86 PCs, or include Apple and Amiga. On the x86 side DRDOS was a minor improvement on MSDOS. DOS was a dead end. So no big loss there. The real competition didn't really start until Windows 3.x era and the only serious competition there was OS/2 and I think you can blame IBM for botching that. IBM was more interested in protecting their own PC hardware than making a superior product for PC clones. IBM was too big and slow. If you consider platforms like Apple and Amiga we see that Apple eventually prevailed, so maybe it was just delayed? I don't know that Amiga necessarily suffered by the MS monopoly. I think they were just too niche.

I cleaned up every file that wasn't "essential" before doing a backup. 41 floppies later, and my backup was done! It had my personal files, Windows system files, everything! Now I use a NAS drive with a ridiculous amount of space on it just to save a fewer number of files that take more space. Does this channel have a video on bloatware?

    Jin KeeJin Kee2 månader sedan
    • By the time Windows 3.1 came out, 4MB was common enough. Windows 3.x it wasn't really an OS (DOS was always running under the hood) but it did have a 386 enhanced mode. IN theory it could access 4GB total (32bit limit), but no one process could be bigger than 16MB. In short, if you wanted a proper 32bit OS on PC back then, you needed to install OS/2 or WIndows NT. Windows 3.x was a broken hybrid.
