How to edit the Windows registry

This suggestion requires the use of the Registry Editor (REGEDIT.EXE). Changes made to the Windows registry happen immediately, and no backup is automatically made. Do not edit the Windows registry unless you are confident about doing so.

What to do

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the Registry menu, click 'Export Registry File'. In the Export range panel, click 'All', then save your registry as Backup.
