I installed the Windows 10 update (updated from 8.1), tried it for a few hours, and didn't like the interface, my mouse driver wasn't working correctly, etc. In any case, I rolled back to 8.1, but Windows update keeps forcing the W10 update down my PC's throat. PC gets hung up on checking for new updates. It is clear that I've tried Windows 10 and didn't want it. Is there a way to stop Windows update from insisting that I download Windows 10?! It's really annoying, it's slowing down my computer.
