SQL Server Management Studio error 0x80070643 - A previous installation required a reboot of the machine for changes to take effect. To proceed, restart your computer and then run Setup again

I recently came up to the error above, when updating my sql server management studio application. Rebooting or forcing windows update, didn't solve the error.
This issue is apparently caused by the presence of this registry entry:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations
This entry should be related to some previous dirty installation. Removing the entry will allow management studio installation to end successfully
