Vista SP1 Rollback Error
Posted 13 years ago on 4/2/2008
 A documented error from our Windows Documented Errors Page


Documented Error:

Service Pack did not install. Reverting changes.

Several members have reported that once they made sure the Windows Modules Installer Service (trustedinstaller.exe) was running, SP1 installed fine. So, if your Windows Modules Installer is disabled and stopped, set it to manual and start it. This WMI Service enables installation, modification, and removal of WindowsUpdates.

General Maintenance
Make sure you have sufficient disk space, run checkdisk, and defrag your hard drive.

Disable Security
Although you shouldn't have to, you might also try temporarily disabling your antivirus software, and firewall. Some members have reported this solved the problem for them.

System File Checker
If that doesn't work, Run the System File Checker Tool. Open cmd and enter sfc /scannow + ENTER.

Required Other Updates
Finally, there are some MS updates that are required prior to installing SP1. With Automatic Updates, they should be installed already but you might wish to double check:

  • 935509 - Vista Enterprise and Ultimate ONLY.
  • 938371 - All Versions.
  • 937287 - All Versions.

Hello my dear friends! Once I needed to write an original essay uk, but I can not write it by myself. So, one of my schoolmates showed me professionals who can do this stuff for me and my assignments were done with the shortest terms. And now I would like to advice to try to buy essays for every student and to use this cool online service!!!
