If i using cleanup tool i can see next:


[Service Pack backup - 530 MB]

I click OK appears progress bar, finishes without errors, but Service Pack backup still not deleted, i can see it if run cleanup again.

Code:

2011-12-26 06:30:47, Error                 DISM   DISM.EXE: Failed to access the image folder or image's windows folder.
2011-12-26 06:30:47, Info                  DISM   DISM.EXE: Image session has been closed. Reboot required=no.

Same error. oh... I think easily to reinstall system

Anyway, big thank you for trying.
