there is no way windows should be taking up 83gb. maybe 30gbs tops, so by the time you install your software you should still have a heap of free space.
Yeah it can... just had one today that had 60GB of temp files in c:\Windows :D
THey only had Office and couple other apps installed.... the temp files were dozens of 5MB log files for Windows Store.... which they dont use for anything.
