Up to Windows 3.11 it was a GUI on top of DOS. Windows 95, 98, Me used DOS to boot and it was still possible to stop the booting process at a DOS prompt (although in Me this was no longer official). Finally Windows 2000 had nothing to do with it as it is NT based.
Windows 2000 was part of the professional NT line, though, and was the companion of Me for the millennium releases. As far as I know, 2000 wasn't marketed to home users. I think what the comment you replied to is saying is the the transition away from DOS wasn't completed for both professional and home markets until XP, which unified everything under NT for all markets.
Around the year 2000, I was studying computer science at a university. Most of their PC's ran on Windows 3.1. I was using it at home. But one day, Microsoft sent me an offer: I could purchase the student release of Windows 2000 workstation for a mere $25.00. I went for it, and found it better than the Windows NT nap-sayers at school said. I don't know why I was contacted. Probbably because of other Microsoft programs I'd bought at the student bookstore.
Windows 2000 was a pretty great OS. Used to enjoy using a Litestep shell instead of explorer. While it wasn't great for a lot of games, many did run fine. I liked it a lot better than OS/2 that I ran previously.
I generally ran 2-4x the amount of RAM as most did. Still do. Pretty sure this made a lot of the difference.
I rain it until it wouln't run sensible anymore in Windoes 10. I then ditched Windows for Linux soon after - I can recommend KDE Plasma if you want to have something thats sorta configureable enough like Litestep was.
Windows 2000 Pro was what I used at home for a long time and it was great. NT 3 and 4 were absolutely terrible which might explain your NT naysayers at school. I never once had to reapply a service pack in Win2k
Still remember the first time I touched Windows NT 4. Half an hour into work experience: Opened up a printer dialogue set a setting that hard crashed the PC; then slowly every other PC in the building as soon as they tried to print (i.e. just as they had _finished_ whatever they were working on; but often just before they _saved_ it).
Can confirm. I upgraded my 98 box to 2000 and never did get some of my hardware working. When I told people I was using 2000 everybody assumed I had stolen it from work. I didn't. My friend stole it from work and shared it with me ;-)
Kind of for a very long while. You then had a descendant SFU from some SP of NT4 to XP / Server 2003, then a further one SUA until Windows 8 / Server 2012. With some code flowing between various companies. I think SFU still used the Posix NT subsystem core. Probably also SUA, although I'm less sure. Not really the case WSL1, though (although probably the core NT kernel was more ready to support it, thanks to its history).
