How to disable about:flags page in Microsoft Edge web browser

Edge browser includes a hidden about:flags configuration page that lets you tweak the browser’s settings. As an administrator in your organization, you might want to prevent this from happening. The hidden flags allow users to enable or change experimental settings anytime and enable experimental features. If you are an admin, you can disable the about:flags configuration page in Microsoft Edge browser on Windows 10, using the Registry Editor or Group Policy Editor.

Disable about:flags page in Edge

Using Group Policy Editor

If your version of Windows 10 ships with the Group Policy Editor, Run gpedit.msc and navigate to the following settings:

Computer Configuration/ Administrative Templates/ Windows Components/ Microsoft Edge

Double-click on the Prevent access to the about:flags page in Microsoft Edge setting to open its Properties box and select Enabled to turn on this policy setting.

This policy setting lets you decide whether employees can access the about:flags page, which is used to change developer settings and to enable experimental features. If you enable this policy setting, employees can’t access the about:flags page. If you disable or don’t configure this setting, employees can access the about:flags page.

Press Apply/OK and exit.

Using Registry Editor

Press Win+R keys to open the Run dialog box. Type regedit and hit Enter to open the Registry Editor.

Now navigate to the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft

Once there, right-click on Microsoft and select New > Key. Name the new key as MicrosoftEdge. If you already find the key by the same name you may ignore this step.

Now right-click on this newly created MicrosoftEdge, select New, and select Key. Name it Main. If it exists already, do not try to create it again.

So the structure will now look like this:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main

Now select Main and in the right panel, right-click in an empty space and select New > DWORD (32 bit).

Name it PreventAccessToAboutFlagsInMicrosoftEdge.

Set the value of this key to 1. This will disable your about:flags configuration page.

software-policies-value

If you would like to enable it again, set the value to 0.

Once done, close Registry Editor and exit.

When you do this, anyone who tries to access the about:flags page, will see the following message:

You can’t access this page. Your organization doesn’t allow it.

That’s it!
