I've repeatedly tried to change my logon screen saver timeout time via
Start | Run regedt32 | HKEY_USERS\.DEFAULT\Control Panel\Desktop\ScreenSaveTimeOut
but although it faithfully stores the number of seconds I want, it keeps actually timing out after 10 minutes no matter what. It wouldn't matter otherwise, but having more than one user accounts necessitates reentering the password for the desired account as if you weren't even already logged in. So how do I make this really work?
