Using the Local Group Policy Editor

The Local Group Policy Editor (LGPE) is a reliable tool for troubleshooting system errors. Interestingly, you can also use it for other tasks such as preventing others from changing your Windows desktop background .

Now, here’s how to use the LGPE to prevent others from installing removable storage devices on Windows:

1. Press Win + R to open the Run command dialog box.
2. Type gpedit.msc and press Enter to open the LGPE.
3. Navigate to Computer Configuration > Administrative Templates > System > Device Installation > Device Installation Restrictions.
4. Double-click on the Prevent installation of removable devices option on the right-hand side.

Select Enabled on the next screen to prevent others from installing removable storage devices into your PC. Alternatively, select Disabled or Not Configured to restore the default settings.

Finally, press Apply and then press OK to save these changes.

3. Click the Restrictions folder, right-click on a blank space on the right, and then select New > DWORD (32-bit) Value. From there, name the value as DenyRemovableDevices and press Enter.
