    Are we talking only on a regularly used home or work machine here or do ATMs, ticket machines and that game console you tried once at a friends house all count? Same question for arcade machines? What about calculators? What about when you call an automated telephone service? Are we only making the distinction on the OS family or would, for example, Windows 95 and Windows NT count as two operating systems? Presumably different Linux distros would count as different OSes too? So many questions! I just about lost count, even going by OS family / primary product name.

        Count all Linux versions as one thing (Although, obviously Yggdrasil ought to count on its own). And all Windows versions is one (But DOS is a separate thing). DRDos and Gem are different - get the idea.

        Do I count real BSD from Berkeley with and without my hacks as two different things?

          That's not really fair. You can't lump Windows'95 in with Windows 8 - they are significantly different beasts in all aspects that anyone encounters.
          Different suggestion: count every version that you'd consider separate as a different OS.
          Sure, it's somewhat arbitrary, but it beats lumping everything from WfW3.11 to Win10 into one category.

          Moreover, as to embedded systems (e.g. microwave, car) or other OS's where you don't really know what the OS is (e.g. NES, SNES, ...): don't count 'em.

          For me, this leads to the following list:
          - ZX Spectrum Basic
          - C64 basic
          - Dos 3.0, 3.1, 3.13, 5.0, 6.0
          - Windows for Workgroups 3.11
          - Windows 95, 98, 2000, ME, NT, Vista, 8
          - Ubuntu LTS: 6.06, 8.04, 12.04, 16.04
          - Ubuntu 7 (i think)
          - Slackware
          - FreeBSD

            That's not really fair. You can't lump Windows'95 in with Windows 8

            I beg to differ. Once set up, there's not THAT much difference between 95 and 7 (I haven't really used Vista much, but when I did, nothing really surprised me. Ten... ten may make me change my mind, tho - I've SEEN some things in Ten, man...)

            Turning off all the thrice-damned "dynamic menu" garbage helps a lot (where am I today? Am I overrr here? NOPE! I'm over here! Can't catch me!), and the Windows-style shortcut keys haven't changed insofar as the really common ones. I can still pop open an Explorer window from anywhere with windowskey+E and then just drill down to the program executable's location.

            Under the hood, yes, there's a lot of changes from 95 to 8 - most of them quite good. From the usability and UI perspective, tho, with a little bit of tweaking using the very options provided within Windows itself, you can maintain a mostly-consistent look all the way from 95 to 8. My Wintendo's desktop and Start menu on 7 looks almost identical to 95, as does the Control Panel and Explorer layout.

            Soooo one needs to define what an OS is as a baseline, and at what point does a derivative count as a unique entity. ( like going from 98 to 98SE should not count as 2 )

        All pre-Mac OS Xes, I counted as one.

        Each separate BSD, I counted individually. But each of the "desktop friendly" BSDs were all considered FreeBSD, so not counted again.

      Side question, bare metal or is retrocomputing simulation OK?

      I know enough OS/8 (the PDP-8 OS, not mac), MVS/360, and TOPS-10 to be dangerous, but I'll never run them on bare metal (probably).

      Let me just throw it out there that TOPS-10 is a cool OS. Long before apple tried to define itself as the friendly computer, TOPS-10 was actually friendly. MVS/360 is technologically impressive but no one would ever define it as friendly, its more of a KafkaOS. OS/8 was written in the 70s for 60s/70s minicomputers and is what 80s first wave home computers SHOULD have had instead of CP/M msdos and TRSDOS. Imagine the progress lost in IT/CS because of 80s home computers. Imagine the progress of a world of $100 PDP-8s running OS/8 instead of $100 commie 64s barely able to run MS basic.

    Hmm first is probably Commodore BASIC
    followed by DOS, I can't remember specific version numbers, but at least 2
    Then the many versions of Windows
    3.1, 95, 98, NT 4, NT 5, 2000/ME, XP, Vista, 7, 8, 8.1, I have so far managed to avoid 10, but it will probably eventually roll out to my work PC.
    UNIX as well as various versions of Linux; Redhat, Slackware, Ubuntu, Mint, Chrome OS.
    A few others, BeOS, FreeBSD.

    Oh and a few MacOS versions starting around system 6 on.

    Many of these were at work/school and were used only minimally, but many of them were installed (usually by me) on my own machines.

    Hmm I voted 16-19 but this looks like more, but it depends on how you count version/revision.

    If you count mobile and other devices, I guess you could also add versions of iOS, android, TI calculator OS, and too many others to count.

    The funny thing is I don't even really think of myself as a computer expert, I just dabble a little.

      Whatever was on th ZX81, then Spectrum.
      Then TOS on Atarti ST
      Then CPM
      Then DOS something early, and VMS.
      Then some very early MacOS, and SunOS
      Then Xenix, DOSes 3, 4, 5, and 6.
      Then Windows 3.0, 3.1, 3.11 for workgroups.
      Then Linux something brutally raw that I didn't install myself, and Solaris
      Then Win NT 3.5, and HP-UX
      Then WIn 95 and Win NT 4.0

      Then whatever Moto had on their phones, S40 and Symbian
      Then Maemo and Harmattan
      Then Gentoo,
      Then Devuan.

      If there's a straight and simple upgrade path between those, I'll not count them as different (So I count 2 windows, 2 Macs, 5 desktop/server linuxes), so I think that's about 20+, but 5 were phone OSes and shouldn't count were it not for 2 of which I use as a computer (n900 and n950), so counting them.

    • Windows NT 3.1, NT4, 2K, XP, Vista, 7~, 8
    • Windows 10 preview (for less than a day)
    • Various early slackware linuces
    • Various early Red Hat (Not RHEL) (I remember they were testing i18n and one of the install languages was "Redneck." Red Hat is in my home state of North Carolina. Very funny guys.)
    • Mandrake (not Mandriva)
    • PalmOS (I actually used the handwriting recognition to take notes and help my memory. Otherwise the Palm devices for me were e-readers.)

      By the way OS-9 is written with a dash instead of a slash. But the real reason I'm commenting is OS-9 is definitely one of my most favorite operating systems. It has a much larger range of machines it runs on than the Tandy CoCo. It's still in use today in embedded systems, etc. Multitasking, real-time, multi-user, reentrant code, etc. Quite a decent OS. I learned a lot playing with it.

      Lots of overlap with my list there. Good poll; my initial guess was likely around a dozen, but when I started to think about phones and other hardware specific options from the early days of micros it went up pretty fast and I got over 20 without the need to count different flavours of Linux, BSD, etc. as different versions; it'd almost certainly be over 50 if I did that. Some other options from my list:

      AIX
      AmigaOS
      BeOS
      DR-DOS
      DyNIX

    I have used various versions of DOS, Windows, Mac, Linux, and '80s home computer OSs, mostly covered by other posters' lists, but I didn't see Amiga yet (I played with MorphOS a bit too). And how about MSX-DOS, Human68K, and whatever OS the TI calculators used?

    It's too bad that the Amiga didn't have memory protection from the beginning. It worked pretty well, in between crashes/gurus/reboots. Of course the 68000 had no MMU, and many 68K-based computer lines were born and died without ever getting a proper protected mode, preemptive multitasking OS. I guess the 68000 suffered from being "good enough." PCs started with the inferior 8086 and were able to move beyond its limitations. Imagine if the 8086 had 24-bit addressing (shift those segments left another four bits). Without having run out of address space so soon (640KB/1MB limit vs. hypothetical 16MB limit), how much longer would 16-bit DOS/Windows have hung on before finally being displaced by Windows NT?

    I guess it depends on how you count an OS. I'm don't think that Linux distros really count as separate operating systems, even if there is increasing divergence over the years. It would be ridiculious to fluff up the count that way.

    • MTS (mainframe)
    • Apple DOS
    • CP/M
    • PC-DOS, MS-DOS
    • DR-DOS
    • MacOS
    • SunOS
    • Windows NT
    • Solaris
    • OS X
    • GNU/Linux
    • OpenBSD

    So I guess that's about 11, not counting ones that I've dabbled with like QNX, HaikuOS, and FreeBSD. Somehow I missed OS/2 completely. I had looked forward to it but after a short wait saw what M$ did to IBM because of it and knew to not expect anything.

    I mean, no one takes these polls too seriously, but I really don't know how to answer. Heck, I don't even know how to count. Windows 3.1, Win NT 4 and Win 10 are surely different operating systems, but what about Win7/Win10? If those count as different, then so must Xubuntu 16.04/16.10/etc.. In which case I may well be in the hundreds by now: Android since the beginning, Windows since the beginning, Linux since, maybe not the beginning but a long time, etc..

    Then there's the question of "used". Being just a pure user of a system, you generally have little contact with the OS.

      I used to ask people what the most widely used file system was, to get them to think a little. Mostly they'd try to foist some bullshit answer like VFAT or NTFS. However, I'd respond with either Google File System or ISO-9660. Back then all computers came with several CDs or DVDs, same for most commercial packages. The world was then full of computer CDs and DVDs, so that would be a case for ISO-9660. However, most people connected to the net use Google at least a few times per day, and that's a lot of people, so that was a case for GFS.

      I'd say Vista and Win 7 are "the same" and that 8 and 10 are "the same". I think that because of how the stuff under the hood is lumped together or presented; like how 2000 and 2003 for server are similar, or 2000 and XP are similar. But 95 and 98 are like each other but not like NT. With that logic, 7 and 10 would be different to me as a result. I am sure some people with only MS experience would lump all of Linux under the same category; just changing the name or version number might not count to someone that has no idea what the differences are.

      But aside from that, I am also confused. There is used, there is actively used, and there is 'exposed to', 'sort of touched once' and 'locked off behind a session on a dumb terminal because I only accessed the program running on the OS and any of the OS gritty details themselves but knew it was on a mainframe or mini computer or x terminal or...'.

      I think for this poll, I'll stick with "devices I had user rights to install stuff onto" as a valid OS. If it was locked in a browser,telnet, ssh or terminal emulator, then that is a gray area -- many CLIs give you access to whats under the hood, yet other ones are no more the OS than dialing into compuserv.

        From my vantage point, XP, Vista, Win7, Win8, Win10, and Server 200x are all various presentations of Windows NT. Thus, same operating system, released with different defaults and added/refined features over time.

        There was windows 1 and 2 that had no memory management to speak of (relying on DOS for that), that were just programs running on top of DOS, and not operating systems in themselves at all, although DOS+Windows was an operating system (just not a very well-supported one).

        Then, there was windows 3.0 and windows 3.1x that had advanced memory management (EMS memory mapping and EMS memory mapping + 386-extended mode memory management, respectively) albeit 16-bit, that made them at least a different thing if not a different operating system, the difference being in the base internals, not so much in the presentation.

        Then Windows 95 through Windows ME, which, still being graphical things on top of DOS, were 32-bit foundations with preemptive multitasking, completely different from what came before, and DOS+Windows 9x/ME being again, arguably, a separate OS.

        And finally, Windows NT / 2000 / Server / XP / Vista / 7 / 8 / 8.1 / 10, an independent system that does not run "on top of" DOS or anything else, but that other things run on top of--arguably a completely different operating system, similar in appearance (initially, anyway) to those that came before: Windows NT 3.1 looked an awful lot like Windows 3.1x despite having almost nothing in common with same, and NT 4.0 looked almost identical to Windows 95.

        I am sure some people with only MS experience would lump all of Linux under the same category; just changing the name or version number might not count to someone that has no idea what the differences are.

        Even the *nix people might have trouble with this one, I guess. Again from my vantage point, since Linux proper isn't so much an operating system as it is a kernel that you make operating systems out of, there have been many operating systems made out of Linux, from Slackware to Debian to Android.

        I would count distinct (Gnu/) Linux distributions as distinct-but-similar-operating systems based on the word "system" being "one thing from many parts" and the parts being different (packages designed for the Red Hat ecosystem, Debian, and Ubuntu, are frequently three different packages because of differences in the underlying OSes involved).

        But the lines here are more fuzzy, sometimes indistinct.

    Honorable mention: that Vulcan minicomputer was a passionate favorite when I was young, 18-21ish, because I had access to source code, and absolutely plumbed the depths of what could be done down in the bowels of the OS. But I quickly moved on to microcomputers when I graduated.

    I developed for UCSD p-System for years. Employer's product (same source code) ran on Apple II, Apple ///, Corvus Concept and IBM PC. The "write once run anywhere" naturally made me like Java many years later. On the IBM-PC we found this Canadian product Datalex Bubble that ran the entire p-System inside an MS-DOS wrapper, so PC users had no idea our app wasn't actual MS-DOS native.

    I developed new versions of employer's product for Mac OS, for years, until the late 1990's.

    Once I learned Linux I never looked back. Timing was convenient because Apple completely abandoned everyone's investment in expensive hardware that ran Mac OS classic. You had to get all new hardware to run OS X. Why bother when there was this new Linux thing.

    3) Various flavors of Windows (and a bit of MS DOS), from 3.1 to 7 (I've briefly touched 8 and 10, but never for more than a few minutes!)
    4) Apple...though I think the only Apple system I ever spent any significant amount of time on was a IIE, and that was just the elementary school labs. Mostly including this to take myself out of the 0-3 category, not sure if it should count ;) Occasionally I also have to support people on Macs, so I've touched OS X a few times, but I generally try to avoid that.

    Not counting each individual Linux distro because that's too easy, I'd be 20+ from that alone...And those aren't really separate OSes, just variants of the same kernel.

    Also not counting different releases of the same OS...might be a new version, but it's still the same OS. Particularly since I'm running a few rolling release, so any attempt to count those would be fuzzy at best.

    And not counting appliances because those OSes don't matter. Sure, I've done a lot of graphics calculator programming, and I've done some game console and digital camera hacking, and I'm sure all of those devices have operating systems...but I can't even tell you the name of it and it's pretty much inseparable from the hardware itself. It's hard to say I've "used" an OS when I don't actually know anything about it!

      The first time I used a computer was playing some kind of educational game on MSDOS before I could even read, so ik not counting that. But early on all windows - 95 ->98 -> ME -> XP. Then it was Mac OSX, and a lot of time playing with an older MacOS (9 I think but can't remember, might still have it though so I should check) box that my dad got when some school sold off all it's old computers. I got into Linux at some point, went from slackware -> debian -> gentoo. Abandoned OSX once I got too used to minimalistic tiling window managers to use screen wasting mouse centric crap anymore. Nowadays I run mostly crux, an OpenBSD box, and I do some routine maintenance on another friend's box which I put Ubuntu on because I got tired of dealing with the viruses and toolbars.
        Mobile, first non featurephone was windows CE, then windows phone 7, then Android, then windows phone 8, and soon I will be back to Android.
      Favorite non-mobile would be OpenBSD, if it had the hardware support of Linux I would use it everywhere, but crux is a nice alternative once I wrote enough Pkgfiles and scripts to get everything I wanted running.
      Favorite mobile would be a tie between wp7 and CE, but the Samsung featurephone I had before those was my favorite touch screen phone.

    Basically, SysV was Unix, before Sco or Berkeley got hold of it. I've used SVr4 and SVr5 - or, they've used me. Industrial embedded systems, which are locked down pretty tightly, to prevent really stupid situations from being created. Our systems have an odd flavor - they don't feel like any other Unix-like that I've ever meddled with. In all cases, SysV has been drastically customized for the machines on which it is installed. Strange stuff, really, but I'm sure that SysV survives outside the plastic moulding industry.

    I entered 8-11, but to get to 8 I needed to count IBSYS as an operating system, and I'm not sure it really counts. OTOH, if TOS does, why not? The TOS machine could also only run one job at once.

    and that was lumping all Linux variants as Linux, BSD variants as BSD, several different RTOSes as RTOS (I know, me bad...) etc.

    Hell, I even left out PRIMOS as
    a. I'd only used it in anger twice
    b. I still feel guilty about the day I was forced to pull the plug on an active Prime system similar to the one in this photo [pr1mehost.com] but a lot bigger with fun things like film recorders etc attached to it, can't recall the model number.

    The system was to be scrapped with zero notice to anyone, I didn't even know the thing existed 10 minutes before I was told to pull the plug on it. I ran into someone almost a decade later who was logged into the system from across the pond (system was in London, he was in New York) when I pulled the main circuit breakers, he always wondered WTF happened that day..bought him several pints as a belated apology, spent the rest of the night getting royally rat-arsed reminiscing about old systems.

    Coming up with this list made me think of things I haven't thought of in *years* - some are probably repressed memories.

    There are some that I've probably missed, but so far:

    IBM S/360 and Amdahl 470 running MTS (Michigan Terminal System)
    HP-1000/RTE
    CDC 6600/6700 running SCOPE
    Interdata running BOSS and SuperBOSS
    PDP/11 running RT-11 and TSX+
    Textronix 4054
    VAX/VMS
    IBM PC compatible running DOS
    Apollo workstation running DOMAIN/OS
    SGI Irix
    Cray running UNICOS
    MacOS
    Windows
    Linux (Slackware, Redhat, Madrake, Fedora, Gentoo, SUSE, Ubuntu, Mint)
    HP-UX
