What is WaasMedic and How to Disable it and Fix it?

WaasMedic or Windows Update Medic Service is a Windows Update component that is run in the background for the purpose of repairing Windows Update should it get damaged or corrupted. This service was newly introduced in Windows 10 so that you can run Windows Update without any issues. Windows updates usually include bug fixes, security patches etc. due to which they become an essential part of the system and if you don’t update your system for a while, you might be vulnerable to many security flaws. The WaasMedic.exe file can be detected as a threat or virus by some third-party antivirus software in which case you should add it as an exception.

You can disable most of the Windows services from ‘Services’, albeit, there are certain services that’ll prompt you with an ‘Access is denied’ dialogue box should you try to disable them.
