WaasMedic.exe, also known as WaasMedic Agent Exe file, can cause high disk usage and slow down Windows. Here is how to fix WaasMedic.exe high disk usage.
To make Windows updates as seamless as possible, Windows uses a special system process called WaasMedic Agent. The official name for this process is “Windows Update Medic Service.” When Windows is checking for updates or installing them, you will see the WaasMedic.exe process running under the “Processes” tab of the Task Manager. Along with facilitating smoother updates, WaasMedic.exe is also responsible for ensuring that all the processes between Windows Update and other components are running smoothly and without conflicts. In general, the WaasMedic.exe process always runs in the background to keep track of all the Windows Update components.
