Enable or Disable About:Flags Page in Microsoft Edge contains two registry files to enable or disable the hidden developer settings. This can also be accomplished using Group Policy Editor.

The about:flags is a hidden page used to change developer settings and allow enable experimental features in Microsoft Edge. These features are often experimental and can change at any time. But, you probably knew all that.

When you enter about:flags in the search bar you probably get an error message that says Well, that didn't work. Your options are to refresh the page, retype the web address, or report this issue. As mentioned, the settings are well hidden and must be enabled.

Double-click on Enable About Flags Page.reg or Disable About Flags Page.reg and restart Microsoft Edge.
