How can I modify the grace timeout for password protected screensavers?

A. When a password protected screen saver starts there is a grace period before a password needs to be entered to deactivate. This can be changed as follows:

1. Start the registry editor (regedit.exe)
2. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
3. From the edit menu select New - String Value from the Edit menu
4. Enter a name of ScreenSaverGracePeriod and press Enter
5. Double click and set to the number of seconds grace period. Click OK
6. Close the registry editor
7. Reboot the machine
