Usually after a clean install, games that require registry keys to be present I can avoid reinstalling by extracting their keys from the old hives or a registry backup.
Has anyone tried a mass registry restore after doing a clean installation of Windows? If yes, which keys to avoid restoring in order not to mess up the OS?
I was thinking a full backup of HKCU and HKLM Software, with the exception of everything from Microsoft except Microsoft\Windows\CurrentVersion\Uninstall.
It would save many of us much trouble, especially when having too many or too large games that would require to be reinstalled, patches to be reapplied, etc.
