I do apologize for my late reply, your posts must have slipped under my radar.
Have you tried doing the SFC /SCANNOW command as described in option two of tis
tutorial? If not, please do it three up to five times
to make sure that it has fixed all possible errors.
If SFC doesn't fix the updating error, you might want to have a look at this
tutorial on how to do a repair install of Windows. Note:
You will not
lose any data or programs during a repair install, but it is still good to have backups of all important files.
Good luck and keep us posted,
