I have Windows Vista Home Premium eddition and itunes 9.......
The default location is "C:\Users\Owner\Music\iTunes\iTunes Music"
I tried to set ccleaner to "exclude" that folder and it still doesnt help....
When I run the CCleaner I lose my itunes playlists. I set it to exclude the itunes music folder but doesn't seem to help. Sometimes I lose the music and have to re-add the folder also. Help!
