Microsoft couple of days ago released a new Preview Build for Insiders in the Fast Ring with some new fixes and features. However after installing the latest Insider build some users started reporting issues with the Edge Browser frequently crashing.

The company has however not mentioned about this issue in the known issues section of the changelog.Now a temporary workaround is provided to fix the crashing issue on the Edge Browser.

Here is how to fix the crashing issue on the Edge Browser:

  1. Use the Windows key + R keyboard shortcut to open the Run command, type regedit, and click OK to open the Registry.
  2. Once the Registry opens, you’ll notice the new address bar that lets you quickly know where you’re in registry, copy and paste the following command in the address bar and press Enter:

    Computer\HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\Children

  3. Right-click each subkey (subfolder) key and select Delete.

  4. Click Yes to confirm the deletion and to complete the task.

Important! Do not delete the Children key, which will prevent Microsoft Edge from starting up, only delete the subkeys.

Once you deleted subkeys manually, you should now be able to launch and use Microsoft Edge on Windows 10 build 14942 without crashes.

Do note that in trying to fix the crashing issue you can end up doing damage to your PC,  hence we suggest you to do a full backup before proceeding with the temporary fix.
