How to prevent users from installing Extensions in Microsoft Edge

You can prevent others from installing extensions in Microsoft Edge using the Registry Editor and the Local Group Policy Editor. Although extensions are supposed to enhance your user experience, at times, they might make things worse. You can therefore block others from installing external or official extensions in the Edge browser on Windows 11/10.

Before getting started with the steps, you should know that this tutorial has two sections. First, you can block the installation of extensions overall, and second, you can prevent others from installing only external extensions that are not available in the official Edge repository or Chrome Web Store.

You will have to first download and add Group Policy Templates for Microsoft Edge. Otherwise, the Group Policy method won’t work.

To prevent users from installing extensions in Edge using Group Policy Editor:

4. Double-click on Control which extensions cannot be installed setting.
5. Select the Enabled option.
6. Click the Show button.
7. Enter * in the Value box.
8. Click the OK button.

To get started, press Win+R, type gpedit.msc, and press the Enter button to open the Local Group Policy Editor on your computer. Following that, navigate to this path-
