My issue is that on my Windows 7 Ultimate desktop, the C:\Windows folder is taking up about 30gb of space. I am currently running off of two 40gb SSD in Raid 0. I'm essentially trying to clean up space due to the fact that my Raid Configuration is pretty much full some how so I figured I'd start where the bulk of the space is being taken up. I've done virus scans, used Malwarebytes, CCleaner, and Advanced System care to try and do some basic clean up. As of right now I only have 7.5gb left out of the 74.3gb total. I'm trying to avoid reinstalling the OS if possible. Also, my main storage is a 1.5tb internal hard drive. Your help is much appreciated.
