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:)
