Enable screensaver on Windows 7

On my current Windows 7 Enterprise 64-bit OS, the screensaver option was disabled: When I right-clicked on the desktop, chose Personalize, the Screen Saver item was greyed out. It also displayed the message at the bottom of the dialog: "One or more of the settings on this page has been disabled by the system administrator."

Some trial-and-error and research revealed the answer.

1. Back up your registry using these instructions.
   
2. Go to Start and in the search box, type regedit
3. This will display the regedit program at the top of the Start dialog box.
   
4. Right-click on the regedit link and choose "Run as Administrator."
5. In regedit, go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new DWORD (32-bit) Value.
6. Name the value NoDispScrSavPage
7. Set the value to 0 (zero).
8. Close the registry editor.
9. Reboot your system.

Now the Screen Saver option should be available again in the Personalize area.

Update: One more step: You also need to follow the steps described here, as recommended by Ted Myers on the Windows Secrets Lounge. Finally, I have my screensaver back :)
