If hypothetically I had a choice today of any Windows OSes with guaranteed ongoing support I’d pick W7.
^^^^ Agreed. The best version of Windows so far. There’s quite a few things I didn’t like about 10 when I tried it. Vista was similar to 7 once tweaked but still a bit less responsive IME. ME was a **** pig and so was the driver support. 2000 Pro alright, although I’ve heard it didn’t do gaming well.
Not switching until another piece of software I use compels it, Septemberish. Still on a pretty old overclocked (oc’d CPU & GPU for the best part of 7-8 years) i5 2500k that runs like clockwork. I’ve not used a windows browser since XP and not bothered with AV for 5 years. It boots in about 20-30 seconds and everything is snappy fast, my GPU (it was all I could get) being the limiting factor in games! I’ve tried much newer builds and mine has been faster in use. I have tweaked a lot of things including the windows bootup and BIOS options, always notified about updates rather than auto. I keep the registry pretty tidy and don’t allow many programs to run on startup or check for updates at ridiculous intervals. I even run custom fan speed curves, how tragic!
