Step 2: Start Disk Cleanup Some important notes from the PFE Blog:
C If nothing is found for Windows Update Cleanup to perform, it will not show up as an option. C After performing this cleanup, you may not be able to uninstall any of the updates currently applied. However, if you need to rollback to a previous version, you can still manually apply the previous version of the update.
Next fire up Disk Cleanup: If you have UAC enabled C Start > All Programs > Accessories > System Tools > right-click on Disk Cleanup and choose Run as administrator . OR If you have UAC disabled C Start > All Programs > Accessories > System Tools > Disk Cleanup . or If you have UAC disabled C press the Windows + R keys and type cleanmgr . Click OK.
If you have UAC enabled: You have to click the Clean up system files button to get to the Windows Update Cleanup option (this basically runs cleanup as admin). Check the box next to Windows Update Cleanup > click OK > after cleanup, Reboot .
Click the Clean up system files button > check the Windows Update Cleanup box > click OK > after cleanup, Reboot. note C If you run disk cleanup as admin the Windows Update Cleanup option will show on first screen.
If you have UAC enabled then check all the options you desire in the first screen > next click the Clean up system files button > check the Windows Update Cleanup box plus any others you desire > click OK .
Press the Windows + R keys > type cleanmgr /sageset:50 . (This can also be run from an elevated command prompt) (note C the number can be any number from 0 to 65535. I use 50 because it is easy to remember.) Click OK.
