On Windows 10, you can disable the Settings app and Control Panel. Here’s how:
To disable the Control Panel and Settings for the current user, navigate to the following keys:
HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Policies.
Navigate to the following keys to disable the Control Panel and Settings for all users:
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Policies.
I’m doing this for the “current user,” but the steps are the same for “all users.”
Click on the Explorer key. If you don’t see it, create it. You can do this by right-clicking on the Policies key and choosing New > Key. Enter Explorer as the name and press Enter.
Right-click on the blank space in the right pane.
Select New > DWORD (32-bit) Value.
Type NoControlPanel as the name, then hit Enter.
Double-click the NoControlPanel. Type 1 in the Value data field and click OK.
If you try to access the Control Panel from now on, you’ll see this message:
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
If you try to access the Settings, then it will not open.
Note: To enable the Control Panel and Settings app, change the value from 1 to 0 or delete the NoControlPanel DWORD.
Now navigate to the User Configuration > Administrative Templates.
Hit the Control Panel.
In the right pane, find “Prohibit access to Control Panel and PC settings” and double-click it.
Select Enabled and then click OK.
That’s it. For the Settings app and Control Panel, follow the steps above, but choose Not Configured or Disabled.
