From the WXPNews newsletter:

When you start Windows, if you don’t click a user name on the Welcome screen or press CTRL+ALT+DEL to log on if prompted, after ten minutes the default Windows logon screensaver will start. You can change this logon screensaver by editing the registry. Here’s how:

1. Click Start | Run.

2. In the Open box, type: regedt32 or regedit.
3. Click OK.
4. In the registry editor, navigate to this key: HKEY_USERS\.DEFAULT\Control Panel\Desktop
5. In the right pane, double click SCRNSAVE.EXE.
6. Type the filename of the screensaver you want to use as the logon screensaver in the Value Data field of the Edit String dialog box.
7. Click OK.
8. Close the registry editor.

Note that if the screensaver file is stored in a location other than the System32 folder, you must type the entire path in the Value Data field.
