Good:
- Windows 95: Loved the Win Plus! themes w/ the screensavers. Mystery is the best theme & screensaver ever. Played Doom II on it.
- Windows 98 SE spent a lot of time playing Duke 3D, Redneck Rampage, C&C series, Diablo, Hexen and anything else I can think of.
- Windows XP. Not much I can say a/b it. It was a fun OS anyways.
- Windows 7. Currently have the Pro version all the way! Win 7 Pro Forever!
Bad:
- Windows NT/2000: When I was fooling around w/ my dad's machine w/ these OS's. I was pissed that Microsoft removed MS-DOS component from that boring as shit OS. I can't play Duke 3D or Jazz Jackrabbit anymore! Why Microsoft WHY!?
- Windows ME: It was prone to crashing and malware. Especially that piece of malware disguised itself as a Weather Bug. Screw ME (not literally! ).
- Windows 8: I never experienced 8 and I never will.
