Maybe so you get:
Start with dvd OS >> Repair Your Computer> Troubleshooting >> Advanced >> symbol system
drums
dir C: \ Windows \ winsxs \ pending.xml
If the file exists is displayed on the screen features. Just delete it, closes symbol system and click Restart.
If to go to suppress gives access denied error, take possession of it first
takeown / f C: \ Windows \ winsxs \ pending.xml
and then you can already remove
the C: \ Windows \ winsxs \ pending.xml
