I never used Win-7 but Win 10 both broke and fixed a few things with Win-8.. I've done 3 Win-10 installs 2 upgrades and an OEM.
I need to tell you about the OEM.. this was a computer I gave as a Christmas Gift to a friend who seriously needed it, Once we got it all set up and working I installed the Free Virtual Fireplace app (Go to windows app store and search for fireplace)
While I had been setting it up she was talking about how much she wanted a fireplace in her "apartment" (there is one in the downstairs, but she (home owner) lives upstairs) So when she found the Fire place app running she was like a Kid at Christmas.
Turns out her cats like to curl up in front of the "Fire" at night too,, She really needs to keep the cats off her bed (Medical reasons) and this works very well.
One of the most useful "Cute" things I'v e ever seen.
