How To Avoid Websites Going Full Screen In MS Edge

If you have invested a considerable amount of money into getting a large display for your computer, getting apps, games, and even websites to run in full screen mode is a big deal. In Windows 10, going full screen in MS Edge and other apps isn’t the most straightforward of tasks. Previously, we covered the method to enable full screen mode for games in Windows 10. Since MS Edge handles a lot of things automatically as well, you can’t just go to a menu to manage its full screen settings. The only solution is to interact with the pop-ups, asking permission for apps to go full screen in MS Edge. If you miss this notification though, there is still a rather obscure way of handling such permissions.

We have a feeling that Microsoft will add full screen mode management in MS Edge in the future. The entries are all there, but you have to go deep inside your system’s registry to modify them. Here is how it works.

  1. Open ‘Run’. This can be done in several ways; through the Start menu or using the search function.
  2. Type ‘Regedit’ and hit Enter. This will bring up the coveted registry editor.
  3. From the left-hand pane, expand the folder named ‘HKEY_CURRENT_USER’ and then go to ‘Software’.
  4. Expand ‘Classes’ and follow the below path;
    Local Settings\ Software\ Microsoft\ Windows\ CurrentVersion\ AppContainer\ Storage\ microsoft.microsoftedge_8wekyb3d8bbwe\ MicrosoftEdge
  5. Now that you are in the MS Edge folder, a lot of its settings can be altered. Expand the folder named ‘Full Screen’.
  6. Under this entry, you can get a list of all apps allowed to go full screen in MS Edge. The list is inside the ‘AllowedDomains’ folder.
  7. Right-click AllowedDomain and hit ‘New’.
  8. Choose the DWORD (32-bit) option.

  • The advice was great up to the ‘expand full screen’ comment. Not sure what they were looking at but I have searched every folder in the registry under ‘Microsoft Edge’ and the full screen folder does not exist so this advice it totally useless
