Windows System Files Taking Up 260GB?

[Endolithic]

System files are taking up 260GB of space. I am very confused.

looks like you need a disk cleanup (set to clean system files) or windows is very confused.

If problem persists, have a look at http://www.fosshub.com/WinDirStat.html

my win 7 x 64 use only 36 gig so you must have os duplication also you could reduce the size of restore point to about 4 to 5 % of the drive .
