I haven't had to do this for 10 yet, but I recall doing it for 7 and Vista a bunch of times.
Well that's good. Yea you wonder why this kept on happening on them. It's annoying to say the least. When it first happened to me, I thought I had a virus on my laptop.
This is what I've been using to help. Thank god for it or I'd be up a proverbial creek

.
Well that didn't work. It cleared it and showed up normally, but it said for me to restart my laptop so it can rebuild. I did that, and ended up with the same mess as before.

It's as if what they were going from cache wise is corrupted some how.
Ugh.
So now onto finding out how to edit my registry to try to fix this.
Found one thing, but it's for Vista. Dammit.
This is annoying. They say how to turn it back on, but when I try to it's greyed out. And I have it set to be on. WTH Windows.
Turns out I had to completely shut my laptop off to get it to load correctly. So saying to reset it is a bit of a misnomer.

On a separate note, I got The Witcher: Enhanced Edition as a gift from a friend via Steam today and I was wondering if anyone else has it via Windows 10. I've heard of some issues with it via installing and such. Wanted to see if anyone else has run into issues with it and what they've done to fix them.
Also, came across
this list of games that are compatible with it.
