just for context, i’ve been daily driving this thinkpad z61m with windows vista sp2 for the past week and it’s actually been pretty damn good lol. sorry, i just don’t like linux that much. though i might post haiku in the future :3 also it’s dual booted with XP Pro SP3 :p
From what I understand, 7 = bugfixed Vista with a different GUI.
the main change was that it came out in an era of faster computers lol
more specifically the 32-bit to 64-bit transition era
that was definitely more of an early 2006 thing, Windows Vista came out in late 06 for manufacturers, but I think it was definitely relevant at the time
