System restart from previous installation or update is pending

Today while installing Sharepoint 2013 Foundation in our web server I faced an error which says: 
System restart from previous installation or update is pending. Restart your computer and run setup to contiue.

I tried restarting but it didn't work and I understood that it's a trap so started what I am good at "Googling" for solution. Here it is:

• Open the Registry editor (run > regedit)
• Navigate to this path “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager“
• Rename the “PendingFileRenameOperations” value to “OldPendingFileRenameOperations“

Note: Don't reboot your machine after this registry hack because if you do then it will again create a key named "PendingFileRenameOperations" and you will be stuck in this vicious circle.
