Windows Software Won’t Uninstall – Reboot Required Despite Rebooting

If this problem happens then it may be a result of failing pending changes to the Windows OS. These file changes are listed in a registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

under DWORD:


I would suggest first renaming this DWORD value, with the prefix “OLD_” or something similar and then attempting the un/install again.

If there were some unexpected results in renaming the file it is trivial to remove the prefix and restore the system but best practice would include an entire registry export prior to fiddling!



Pending File Rename Preventing Install

I had to install some Dell software but kept receiving the message “Unable to complete the installation due to pending file rename operation” on Windows 10 Enterprise.
Renaming the registry key HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperationsOLD allowed me to complete the installation.
