I'll concede you can't do that from within Win10 itself. However, there are a few programs that will allow you to have it back. One such program is
http://www.glass8.eu/ I personally prefer non-aero look. I always disabled it back when I used Win7.
However, let's go back to my other 3 points you seemed to forget.
1. Telemetry: Do you have a smart phone, use Facebook etc? If so, you have no right at all to say anything about Win10. If you took the time to actually read what MS collect, it's 100% OS based. The personal info they do collect is basic shit people could pull from Facebook.
2. Forced services: If you're on about windows updates being forced on home edition, I don't blame MS in doing so. When I worked in retail, selling PC based shit, the amount of customers that would bring a PC in that hadn't been updated in years was insane. We once had a customer in who didn't update his PC at all, and got malware installed that fucked his PC up. Best part about it was THERE WAS AN MS UPDATE FOR IT 6 MONTHS BEFORE. But apparently it was microsoft's fault his PC got AIDS, then it was OUR FAULT because it should auto update and we didn't set it up to do that.
ALL MY WATS.JPEG
3: Running slow. Maybe if you're using a Pentium D and 128MB RAM. Little bit of info here, Win10 runs BETTER than Win7 and Win8 on lesser hardware.
But hey! it was just my job to fix shit, what do I know?
