I installed the Windows 7 Ultimate Edition over the existing Windows 7 Tweaked Gamer edition which had a lot of bugs and minor issues here and there.
Not able to delete the Windows.old and Windows.old000 folder which were automatically created, due to some issue with access permissions. Moreover there is a huge clutter of folders in the C: which are now of no use. These folders were not removed during the install and Windows is not allowing me to delete them now.
I guess I’ll format C: and again install a fresh copy of windows through USB into it to clean up all the clutter. zzZZ…
Done. Laptop is as good as new .
