In my laptop the screensaver disable (desktop->right click->properties->screensaver tab) thing is greyed out and time is set to 10 minutes. I cannot modify this as it is greyed out. What can i do ?
I have admin rights over my machine.
Changing "ScreenSaveActive" data key to zero will disable default screensaver and if you ever wish to enable it back again, simply follow the procedure and set the value to 1.
