On Windows 10 there are dozens of different ways you can restrict and block access to important parts of the operating system. Although most users won’t want to or need to block access to these specific services and features, there are plenty of situations it can be useful, especially if you have a shared PC.

In the past we have covered how to hide specific settings within the Control Panel, however, this guide will take that one step further and show you how to completely block access to the Control Panel and Settings App, not just specific items within them. So without further adieu let’s begin.

How Do You Block/Restrict Access to the Control Panel and Settings App on Windows 10?

Before starting the steps shown below, it is important to make sure you have created a System Restore point, in case you need to revert back to a previous system state. If you’ve never created a restore point before do the following. Open the start menu, type Restore, then select Create a Restore Point when it appears on the list. In the new window that appears on the screen, click Create in the bottom right section of the screen, then follow the on-screen instructions. Once you have a restore point set, continue with the steps shown below.

With a safe point set, open the Windows Registry Editor by pressing Windows Key + R, then type regedit into the Run tool text box and press Enter. When you have the tool open in front of you, navigate to the following location using the left-hand pane of the Registry Editor.

Control Panel, on the other hand, will show the following restriction message. If at any stage you wish to reverse the restriction, simply return to the same registry location and change the value of NoControlPanel to 0. Alternatively, you can delete the entire NoControlPanel entry.
