Click Reset again, then restart your computer.

Try Administrator Mode

Sometimes permission issues prevent Internet Explorer from starting. Right-click the Internet Explorer icon on your desktop or taskbar. Select "Run as administrator." This grants full system permissions and often fixes won't launch problems instantly.

If none of these steps work, Internet Explorer may have core system file damage. Consider using an alternative browser like Chrome or Edge instead!
