@Nezchan This is where all the configuration files are kept. I suspect the issue you're having with windows because there's some stray setting somewhere that makes this happen.
I'd carefully examine what grep returns (it returns matching patterns and file names where it finds them).
I'd open the files it returns with text editor and see what they contain.
Deleting *some* of these files will reset your settings, but this will reset all of your settings and can mess with other system params.
