I was on my computer today and edited the username on my account on the computer, i also disabled read only on my account to make a program work, but it didn't, so i enabled read-only on the account once more.

But then some of my OPEN programs, like SKYPE, started to run very slow, i tried to restart skype, but when i tried to re-log it said I/O error on disk, i tried to restart my computer, but then other programs stopped working too, my spotify crashed right when i tried to start it, and everytime i  closed google chrome and started it again it said "Google chrome wasn't shut down correctly", and was offering me to restore my LATEST session. i even tried to system ROLLBACK my computer 2 days, but my programs still doesn't wanna work, now i'm out of ideas.

Does anyone know how to fix this?
