The problem is plain and simple:
I'm using Windows XP Professional at my home computer. I've made two accounts, one with administrator rights and one without administrator rights.
When I right click the desktop and choose Properties, I can change the Display Properties (duhh). In the Screensaver tab I can click the button Power. Now, when I'm logged in as the user with limited rights, I can only choose from the predefined power schemes. When I change the time after which the monitor and harddisk should turn off, and I click Apply, I get an error message. The window title of the error message states "Power Policy Manager unable to set active policy". In the error message it says "Access is denied".
However, when I'm logged in as administrator I'm able to make changes to the predefined power schemes and save the changes in a new power scheme. But this newly saved power scheme isn't available to the user with limited rights.
How can I change the policies, so that a user with limited rights can save its own power scheme?
Or, how can I make the power scheme of the administrator available to other users?
