How to stop Microsoft Edge from crashing at startup

Important: Before proceeding with this guide, you should know that modifying the registry is risky, and it can cause irreversible damage to your installation if you don’t do it correctly. It’s recommended to make a full backup of your computer before proceeding.

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.
