How to Power Options as a non-administrator on Windows XP

The “Power Options” Control Panel applet is not usefull for non-administrators because clicking “OK” causes per-machine and per-user settings to be written, the only way to change the per-user settings is if the user is an administrator.
The solution are to make users able to write on selected key-reg

  • Run Regedit.exe as an administrator
  • Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg
  • Right-click on the “GlobalPowerPolicy” key and choose “Permissions”.
  • Click on the “Advanced” button.
  • Click “Add”.
  • Type INTERACTIVE and click “Check names”, then OK.
  • Check the “Set value” and “Create Subkey” checkboxes in the “Allow” column, and click OK, then OK, then OK.
  • Do the same thing with the “PowerPolicies” key.

No reboot is required. You can now manage your own power options without needing to be an admin.

To do the same thing via batch…

subinacl /subkeyreg "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\GlobalPowerPolicy" /grant=Users=f
subinacl /subkeyreg "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies" /grant=Users=f
