Well actually was not really knowing that /programData would be so much important.
Actually, I thought while any service/app runs, it saves its config/some sort of settings there (which was wired I think now). Like for some apps, some sub-folders are getting created now.
- I was clean the system from some /temp, unwanted files.
I believe restore/re-installing the Win7 is now the only option.
AnyIdea, how to keep backup for Imp files in C:\. Any best practices for backup?
