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:
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!
