Hi. C drive's about 20 gigs and I couldn't manage to have disk space more than a gig. Turned system restore, hibernation off and cleared all the temp files using disk cleaner and other softwares. Very few softwares have been installed. There's a lot of space in other drives. So, what should I do? Just reinstall, or is there any other way to save disk space? I've turned Windows Update on and is it gonna affect my disk space??? Need help.
