Only administrators have the permissions and rights to alter the Power Options / Power Schemes settings on a Windows 2000 Professional computer.
If you wish to grant an ordinary user the right to alter the Power Schemes:
1. Grant the user the right to Shut down the system (Control Panel / Administrative Tools / Local Security Policy / Local Policies / User Rights Assignment). Add the user or group to this local security policy. If SP3 or later is applied, also grant Create Pagefile rights.
2. Use Regedt32 to navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\GlobalPowerPolicy.
3. On the Security / Permissions menu, add the user or group and grant them Full Control on this key.
4. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies.
5. On the Security / Permissions menu, add the user or group and grant them Full Control on this key.
NOTE: To do this remotely, use NTRights to grant SeShutdownPrivilege and SeCreatePagefilePrivilege rights. Use SetACL or RegDACL to set Full Control permissions on the registry keys. Use PsExec or Workstation.bat to run a batch remotely.
