Control which extensions cannot be installed

List specific extensions that users can NOT install in Microsoft Edge. When you deploy this policy, any extensions on this list that were previously installed will be disabled, and the user won't be able to enable them. If you remove an item from the list of blocked extensions, that extension is automatically re-enabled anywhere it was previously installed.

Use "*" to block all extensions that aren't explicitly listed in the allow list.

If you don't configure this policy, users can install any extension in Microsoft Edge.

Example value:


Supported on: Microsoft Edge version 77, Windows 7 or later

Extension IDs the user should be prevented from installing (or * for all)
