How to Prevent Installing Extensions in Microsoft Edge

It’s been more than an year since the Windows 10 Anniversary Update was released and Microsoft Edge got extensions support. Till date there are only 60+ Edge extensions available at the Windows Store, which is very less compared to the number of extensions available for mainstream browsers like Chrome or Firefox. Also, there are non-Store extensions that you can side-load into Edge.

Edge extensions support can be enabled or disabled using the Local Group Policy Editor or the registry. If you’re the administrator of a computer and want to prevent users from running extensions on Microsoft Edge, this guide has the instructions.

Method 1: Block Edge Extensions Using the Registry Editor.

Here is how to use the Registry Editor to prevent installing Edge extensions:

  1. Right-click Start, click Run. Type regedit, and click OK.
  2. Navigate to the following branch:
  4. Under Microsoft, create a new key named MicrosoftEdge.
  5. Under the MicrosoftEdge key, create a new key named Extensions.
  6. Select Extensions, and create a new DWORD (32-bit) Value named ExtensionsEnabled
  7. edge extensions disable registry

  8. Let the value data of ExtensionsEnabled be 0.
  9. Exit the Registry Editor.
To accomplish the above registry setting using command-line, open an administrator Command Prompt window and type:

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Extensions" /v ExtensionsEnabled /t REG_DWORD /d 0

Press ENTER.

Edge extensions are blocked now. You won’t be able to use existing extensions or install new extensions in Microsoft Edge. Also, the Extensions option in Settings will also be disabled. With Edge extensions support disabled, Windows Store still allows you to install Edge extensions, but they won’t load when you open Edge.

Method 2: Block Edge Extensions Using the Local Group Policy Editor

If you’re using Windows 10 Pro or higher, you can configure the setting using the Local Group Policy Editor (gpedit.msc). The above registry setting corresponds to the Allow extensions group policy, located under the following branch:

Computer Configuration > Administrative Templates > Windows Components > Microsoft Edge

This setting lets you decide whether employees can load extensions in Microsoft Edge. If you enable or don’t configure this setting, employees can use Edge Extensions. If you disable this setting, employees can’t use Edge Extensions.
