If I perform a PC Reset/Reinstall of the operating system, retaining my files, but not my installed programs, which directories are kept safe, and which directories should I back up? I'm looking for a comprehensive list, so that I can make sure I minimize the amount of files I have to sift through but also don't lose data that some of my apps install into, for example, the %APPDATA% or %LOCALAPPDATA% directories.
For background, my Windows installation seems to be corrupted—it was probably corrupted from the start, since a few programs (such as GeForce Experience) never worked right from almost the beginning, but it got worse when I tried uninstalling the Virtual Machine Platform feature since disabling Code Integrity & memory scanning from the Settings dialog didn't fix anything. This broke things severely, though the computer is still limping along for now.
Since it doesn't seem that there's a chance I can just go in and prune the settings to fix whatever broke earlier (since reinstalling Virtual Machine Platform didn't change anything), I think my only option is a PC reset, but I don't want to lose data from my programs that aren't backed up to the cloud already.
