Of course, at the beginning, you must exclude the computer from the region where the policy is applied. If the policy is still active at the computer, you cannot change any setting applied with GP.
After GP is disabled, you must change few values in the registry:
- 1. The registry key HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem
- ScreenSaverActive for Enable (1) or Disable (0) screen saver
- ScreenSaverIsSecure for Enable (1) or Disable (0) password protected screen saver
- ScreenSaveTimeOut for number of seconds that the screen saver will be going on
- 2. The registry key HKEY_CURRENT_USERControl PanelDesktop – I suggest to view and set up the same values also here (keys are very similar), but this is not a group policy setting; it is a normal windows setting.
Remark 1: I found in some cases also an another registry key to be modified: HKEY_CURRENT_USERSoftwarePolicesMicrosoftWindowsControl PanelDesktop. Please look also at this point..
