- Even if you disabled extensions running in the background when Edge is closed, some extensions might be sneaky.
- Open Microsoft Edge and go to Settings (three dots menu) > Extensions.
- Review the list of extensions and disable any you don't actively use.
Edge might be running as a service in the background. You can check and manage services by typing "services.msc" into the Windows search bar and pressing Enter. Look for any Edge-related services, such as "Microsoft Edge Update Service," and set their startup type to "Disabled" if you want to prevent them from running automatically.
