|Regedit||Regedit is a commonly used editor (provided with Windows) for accessing the Windows Registry. It can be accessed from the Start Menu ( START > Run > type "regedit" ). Many of the registry values require rebooting the PC before they take effect.
Note: Modifying some registry settings can cause serious problems and damage your operating system to a point where it needs to be reinstalled. Make backups and use the information at your own risk.
Again, backup the Windows Registry before changing anything !
