Exchange 2013 Update 6 fails to install pending reboot no matter how many reboots are done

I attempted to apply Update 6 for exchange but the update countinued to claim a reboot was needed.

I found a site that listed keys to delete:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

However those keys did not exist. I did find a reference to pendingfilerenameoperations in a key called Pending Rename Operations that was located in a HKLM\SYSTEM\ControlSet002\Control\BackupRestore \KeysNotToRestore

After removing that reference from the registry the update is not installing.

My question is what hole have I dug for myself in doing this? There didn't seem to be anything on this I could find other then a 2003 site that said absolutely do not remove keys from that location!

Try using the sysinternals tool pendmove.exe from the following link


This will tell you why your system shows the reboot is pending and what file needs to be replaced or deleted.

Syntax is given in the link.

But it was in the KeysNotToRestore part of the registry so what I think was happening was the update was seeing that key and that it was not empty and thinking it was an actual unresolved update but it was not.

The update worked and fixed one of my other issues with user not sending email with OWA.
