Type appwiz.cpl into the Run window and click on OK. 2. In the Programs and Features window that appears, select Turn Windows features on or off. 3. Scroll down in the Turn Windows features on or off window and check the box next to Windows Sandbox then click on OK. 4. A new window will appear that will start searching for required files. Once complete, the computer needs to be restarted to complete. Click on Restart Now to start this process. Once restarted, the computer will show an updating Windows screen. 5.
