Posting my question on this forum on a recommendation from a Microsoft Support Engineer. I kept the same title for easy cross referencing. I'm having trouble on a Vista box to cancel an update that is rebooting my machine. Tried all suggested methods described in the original thread below with now success. Rather than repeating all the steps here is the original thread: http://answers.microsoft.com/en-us/windows/forum/windows_vista-system/vista-reboots-when-trying-to-configure-updates/f977483a-8b93-4f85-9508-c6520d28ff03?page=1&tm=1326659129127 If the forum prefers me to copy the content of that thread in this forum, I'll do it. Any help is appreciated. Really stuck here :-( D.

Is your Windows Vista DVD media with SP1 or higher? SP1 is a prerequisite for DISM. Regards Milos

Unfortunately, it's pre-SP1 (MS Vista Ultimate - without SP1). Any other way to cancel the scheduled update? When I tried to rollback to a previous checkpoint, it didn't find any on the C drive. D.

Looking at the recommendation from the original post, try this. Although your Vista disk is pre-SP1, you can download Microsoft's Windows 7 Enterprise trial: http://technet.microsoft.com/en-us/evalcenter/cc442495 (this is a fully functional version that expires after 90 days from install--but it can be a very useful aid in recovery operations). Once you boot with the Win7 trial disk, follow the below instructions from your original post. =================== Method 2: If the issue is not resolved, I would suggest you to follow these steps and check if it works: a. Open command prompt tool in the Windows Recovery environment mode. b. You'll see X:\Sources c. Type “DISM /Image:C:\ /Cleanup-Image /RevertPendingActions” without quotes and pressEnter. e. Exit from the command prompt and restart the computer. =================== Good luck.

Tried it and I'm getting the following error: DISM version: 6.1.7601.17514 Error: 50 The command specified is unknown or not supported when running DISM.exe against a Windows Vista with Service Pack 1 or a Windows Server 2008 target image. For more information, see the Help documentation available in the Windows Automa ted Installation Kit <Windows-AIK> or the Windows OEM Preinstallation Kit <OPK>.

Any other suggestion? D.
