All of a sudden, after my bride used my desktop, it looks like I have a new Windows Theme. I've gone through all the themes and settings, and can't get it back to normal. The screen is weird to say the least. All my folder icons are light yellow now. What's going on? I've ran SFC a few times with rebooting. Any way I can use a .bak Registry file to restore it? I can't even find that. I'm running Windows 10 as a upgrade from Windows 8.
