I'd actually say it was 8.1, but the problem with 8.1 is that it died before people could discover how good it is combined with classical start menu. It was basically a fleshed out, faster, more stable Windows 7 with updated tech like newer directx and cached boot (aka. Fastboot). Almost non-existing market share, but I liked it far better than 7, 10 and 11 (only gave it 1 week). I installed a tweaked 8.1 version on all my friends/family's PCs and never heard a single complaint, shit was awesome.
