I've been using it for a year+.
After restoring the left-side taskbar and classic mouse context menu, it's way better that Windows 10, faster and less buggy.
Win+X menu brings a decent quick menu, also admits keys for faster access.
The only really annoying thing is window combining/grouping, it's enabled by default, there was a registry hack but was later removed, use Win+tab as alternative.
W10 had serious issues every then, now and tomorrow, stuff breaking after updating was common, also I hated so much the black UI, a little worse and they would have go back to Windows 3.1.
Still, I prefer Windows 7 by a lot, would use it if companies didn't make such big efforts to make it obsolete.
My system has uncompatible CPU (i7-3770k) neither TPM, yet I get all updates, although McrappySoft said unsupported machines wouldn't get them.
I'd say: Give it a try!
