Hi nls_blisk,

Thank you for visiting the Microsoft Vista Community Forums.

Please do this.


1) Boot in Safe Mode, open SERVICES Window , stop Backgroung Intelligence transfer Service, Cryptographic Services, and windows update services.

2) Rename "Software distribution" folder located in C:/ Windows/Software distribution to 'Software distribution.old" and catroot2 in C:/Windows/System32/catroot2 to "catroot2.old".

3)Perform a clean boot in MSCONFIG by unchecking "load startup items" and disabling all 3rd- party services.

4)Check for "pending.xml" in C:/Windows/Winsxs folder and delete it.(Sometimes you may not be able to find it).

5) Remove any Security programs (Antivirus or Anti Malware or firewalls) and restart the computer and check for updates , once you see the SP2 update start installing it again. That should work without any issues.

Hello, umangsharaf

Were you able to successfully do a system restore and boot into Windows normally?
Are you able to boot into Safe Mode correctly?

We look forward to hearing back from you.
