Toggle Access to Control Panel

SUMMARY: If you need to disable access to the Windows XP Control Panel or restore disabled Control Panel access, perform this tip.

If you are configuring a Windows XP computer for new users or for public use, you may wish to disable access to the entire Control Panel so people cannot accidentally change settings that may cause problems such as making the screen unreadable, disabling devices, and disabling security features such as the Windows Firewall.

Conversely, you may be the victim of a spyware or other malware attack, or system files may have gotten corrupted, preventing access to the Control Panel. You may not even see a Control Panel option from the "Start" menu. This Registry tweak may solve your problem.

1. Open the Windows Registry Editor (Click "Start" - "Run" - "regedit.exe").

2. Navigate to the following key:

My Computer \ HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer

3. To prevent Control Panel access (you will not even be able to run .CPL files manually), create a new DWORD value named NoControlPanel with a value of 1.

To re-enable Control Panel access, delete the NoControlPanel value.
