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).

One had to be a bit savvy to jump through the hoops but ultimately it wasn't inaccessible to your average teenager.

    • 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.

    TJEssaryTJEssary28 dagen geleden
    • 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.

    wwazmanwwazman29 dagen geleden
    • 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.

      YarnoshYarnosh25 dagen geleden
  • 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 FirewalkMaand geleden
    • 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 KeeMaand geleden
    • 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.

  • Hi fellow nerd! I've got a story for you. But I believe it is probably too long to post as a comment. The short version is "I was there". I will email you with details. I was hanging out with a bunch of folks in the Scotts Valley, CA area (where Borland, International, as they were called back then, was located). Andrew Shulman and others you mentioned attended some of the same social engagements and we all often compared notes. I discovered what I refer to as "Novell NetWare/DR-DOS subverting code" while working on an update to TurboPower Software's TurboPower Utilities. These were a set of public domain tools written by TurboPower president Kim Kokkonen. I was the 3rd employee at TurboPower and Kim asked me to figure out why his mark/release pair of utilities for managing Terminate-and-Stay-Resident (TSRs, aka DOS popup utilities) didn't work with the NetWare driver. That NetWare code ran as a TSR back around late 1980s/early 1990s and you could not unload it once loaded even using Kim's clever utilities. He asked me to research and update this code to work with NetWare, which was the most significant player in local area networking pre-Windows NT. Finding the solution involved tracing the operating system's entire bootstapping and executable launching code. I found the checks that triggered messages such as the one in this video by watching the OS unravel at runtime and not via some static analysis of disassembled code. It was bigger than just this error. I was a young, arrogant hotshot and had no trouble walking up to Bill Gates, Brad Silverberg at Microsoft, or Eric Schmidt (then CEO of Novell) or Drew Major (one of the 3 original architects of NetWare). Soon after this I was recruited away from that wonderful job with TurboPower to work at Symantec where I created LiveUpdate and worked on many amazing projects through the rest of the 1990s. There's a lot more I could tell you but I am not sure how much to say publicly. I am being diplomatic with my wording here. Back then, I was mad as hell that an operating system vendor would target a rival company's code and sabotage it from loading for no customer-serving reason. The mad as hell part and my followup actions once discovering this code are the parts I don't necessarily want to discuss in public. I'm glad I clicked on this video when NLworld algorithm decided to put it recommended videos!
