Microsoft Edge extensions support can be enabled or disabled using the Local Group Policy Editor or the registry. If you’re the computer administrator and want to prevent users from running extensions on Microsoft Edge (Chromium), this guide has the instructions.<\/p>\n

Prevent Installing Extensions in Microsoft Edge<\/h2>\n

Method 1: Block Edge Extensions Using the Registry Editor.<\/h3>\n

Here is how to use the Registry Editor to prevent users from installing Edge extensions:<\/p>\n

    \n
  1. Right-click Start, click Run. Type regedit<\/code>, and click OK.<\/li>\n
  2. Navigate to the following branch:\n
    HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft<\/pre>\n<\/li>\n
  3. Under Microsoft, create a new key named Edge<\/code>.<\/li>\n
  4. Under the Edge<\/code> key, create a new key named ExtensionInstallBlocklist<\/code>.<\/li>\n
  5. Select ExtensionInstallBlocklist<\/code>, and create a new String (REG_SZ) value named 1<\/code><\/li>\n
  6. Double-click 1<\/code> and its data as *<\/code>
    \n\"block<\/strong><\/li>\n
  7. Exit the Registry Editor.<\/li>\n<\/ol>\n
    \n
    To accomplish the above registry setting using command-line, open an administrator Command Prompt window and type:<\/p>\n
    reg add \"HKLM\\SOFTWARE\\Policies\\Microsoft\\Edge\\ExtensionInstallBlocklist\" \/v 1 \/t REG_SZ \/d \"*\"<\/pre>\n
    Press Enter<\/kbd>.<\/p>\n<\/div>\n
    Microsoft Edge extensions are blocked now. The existing extensions don’t load when you open Edge. And, new extensions can’t be installed – whether it’s from Microsoft or external sources. You’ll see the message “Your admin has blocked “extension_name”<\/strong><\/em>. You’ll also see the Managed by organization<\/a> notice in settings.<\/p>\n
    \"block<\/p>\n
    The edge:\/\/policy<\/code> page<\/a> would show the list of policies applied and the corresponding values.<\/p>\n
    \"block<\/p>\n
    Block selected extensions only?<\/h4>\n
    You can also block individual extensions instead of all extensions. The wildcard character *<\/strong><\/code> denotes all extensions. To block particular extension(s) only, you’ll need to use the extension ID as the data, and create additional values 2, 3, 4, and so forth – for each extension you want to block.<\/p>\n
    The extension ID is found in the Microsoft Edge Addon store URL itself. For example, here’s the “Adblock Plus” extension’s store URL, and its ID is specified below in bold letters:<\/p>\n
    https:\/\/microsoftedge.microsoft.com\/addons\/detail\/adblock-plus-free-ad-bl\/gmgoamodcdcjnbaobigkjelfplakmdhh<\/strong>?source=sfw<\/pre>\n
     <\/p>\n
    \n
    Want to block only external extensions?<\/h4>\n
    There is another registry setting using which you can block only external extensions. Extensions that are not loaded from the Microsoft Edge Add-ons store are referred to as externally installed extensions.<\/p>\n
    To block external extensions (only), use the BlockExternalExtensions<\/code> registry value (instead of ExtensionInstallBlocklist<\/code>)<\/p>\n
      \n
    1. In the Registry Editor, go\u00a0to the following branch:\n
      HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft<\/pre>\n<\/li>\n
    2. Under Microsoft<\/code>, create a new key named Edge<\/code>\u00a0if it doesn’t already exist.<\/li>\n
    3. Under the Edge<\/code> key, create a new key named BlockExternalExtensions<\/code>.<\/li>\n
    4. Select BlockExternalExtensions<\/code>, and create a new String (REG_SZ) value named 1<\/code><\/li>\n
    5. Double-click 1<\/code> and its data as *<\/code><\/strong><\/li>\n
    6. Exit the Registry Editor.<\/li>\n<\/ol>\n<\/div>\n
      Method 2: Block Edge Extensions Using the Local Group Policy Editor<\/h3>\n
      If you’re using Windows 10 Pro or higher, you can install the Microsoft Edge (Chromium) group policy templates<\/a>\u00a0from Microsoft. Once you’ve added the administrative template files msedge.admx<\/code> and msedgeupdate.admx<\/code>, you can configure the above settings via the Local Group Policy Editor (gpedit.msc<\/code>).<\/p>\n
      \"edge<\/p>\n
      Computer Configuration \u2192 Administrative Templates \u2192 Microsoft Edge \u2192 Extensions<\/pre>\n
      Under the above branch:<\/p>\n
      1) The ExtensionInstallBlocklist<\/code> registry key corresponds to the group policy “Control which extensions cannot be installed”.<\/p>\n
      Lets you specify which extensions the users CANNOT install. Extensions already installed will be disabled if blocked, without a way for the user to enable them. After a disabled extension is removed from the blocklist it will automatically get re-enabled.<\/em><\/p>\n
      A blocklist value of ‘*’ means all extensions are blocked unless they are explicitly listed in the allowlist.<\/p>\n
      2) The\u00a0BlockExternalExtensions registry key corresponds to the group policy “Blocks external extensions from being installed”.<\/p>\n
      Control the installation of external extensions.\u00a0If you enable this setting, external extensions are blocked from being installed.\u00a0If you disable this setting or leave it unset, external extensions are allowed to be installed.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
