In my mind the Win7 start menu was broken and I never figured out how to use it.
I liked Metro, no more cluttered desktop, no more start menu bigger than the screen and easily navigated with a keyboard. I did hate it at first, however.
I got a Windows 95 vibe from Win8, it was a transitional OS, a move into the new era. Far from perfect, but necessary. Windows 10 will therefore be Windows 98; it won't work and they'll have to release a Second Edition that people will install on EVERYTHING. Hey, why's this 486SX-25 so slow? Oh wait, you installed Windows 98... err... Windows 10 on it.
Then people will get needlessly defensive of it "It's NOT windows, you're wrong, you don't know what you're talking about, you're a fucking idiot!" - I got tired of this in the Win98 era. I had this lecture from a guy who had somehow got Windows 98 running on his 386 - don't ask me how - and it was of course the fault of the computer system for not working well and I was a "fucking idiot" for telling him to install something else, like DOS, or get a new computer. Used to be a lot of people like that, they were the real idiots though and I used to bill them for shit I hadn't even installed because I wasn't allowed to argue with them. Oh, well, it paid for upgrades on my machine anyway.
