I'd just like to point out a tool that I have been using for many years that has pulled my bacon out of the fire more than once. It's the Windows All in One Repair tool from Tweaking.com
This has fixed when viruses have disabled exe files, stuff has been broken in the windows store, registry entries have broken permissions, bad fonts, the list just goes on and on.
IMHO, every tech should have this tool in their arsenal.
Back to your regularly scheduled bugs. :)
Just my $.02
