Windows 7 : Missing 50GB

[Doge Verm]

I cleaned the prefetch folder , cleaned the %temp% folder and ran CCleaner but I am still missing about 49GB, Im not all that familiar with system storage yet (studying)

Any help/clues why Im missing 49GB?

Check Backup and Restore in Control Panel and look what Windows is taking for System Image and its Backup Images. That would be a good start. Run cleanmgr.exe Windows Drive Cleanup Tool for other folders.
