tl;dr : rstrui.exe is missing from my system tools folder in the Start Menu, how can I get the shortcut back?
My desktop background didn't want to change (it went to black, and stayed black no matter what), so I decided to do a System Restore. I went to the start menu, all programs, accessories, system tools.... No system restore. Missing.
I did manage to do the good ol' F8 trick while starting Windows to use the system restore; backed up to my programs from yesterday. My desktop background decided to start working again, so one less loose end.
I don't fancy going through my system32 folder just to restore, so can someone tell me how to get rstrui.exe back in my system tools folder as a shortcut?
