WaaSMedicAgent is responsible for repairing Windows Update when it fails. Unfortunately, Medic Agent itself can cause problems by having lots of RAM, lots of CPU, and lots of disk usage. Fortunately, WaaS MedicAgent can be completely disabled.

What Is WaaSMedicAgent.exe?

No software is perfect – things go wrong and files get broken, including windows updates ( especially the updates of Windows ). Windows as a Service Medic Agent (WaaSMedicAgent) was introduced in Windows 10 to “Enable the correction and protection of Windows Update components”. In other words, it fixes problems with Windows Update that might be preventing your PC from updating.

This process is supposed to run when Windows encounters a problem with an update. Unfortunately, Medic Agent itself has been known to cause problems. In some cases, it bogs down PCs for hours by maximizing CPUs, leading to extremely high RAM usage and high disk usage.

delay your updates

WaaSMedicAgent should only be activated if Windows Update finds a problem. pause the windows 10 updates either Windows 11 can temporarily prevent WaaSMedicAgent from using excessive amounts of RAM, maximizing your disk usage, using up your CPU, and bogging down your PC. However, it will not permanently solve any of your problems.

If you just need your system to work for a bit, pausing updates is a good option. Just remember to let it run later so it can try to fix any errors that occurred.

Disable WaaSMedicAgent using RegEdit

WaaSMedicAgent is the Windows service associated with WaaSMedicAgent.exe; if you want to stop the executable from running, you must also disable the service. Windows will not allow you to disable the service from the Services application, but you can disable it using Registry Editor (RegEdit). As always, be careful when editing the Windows Registry. Accidentally deleting a key, or even changing a value, can cause serious problems for computers and major headaches for humans.

First, you need to start RegEdit. Click the Start button, type “regedit” in the search bar, and then press Enter or click “Open”.

Press the Start button and then click

Navigate to the following path in the Registry Editor window, or copy and paste the following line into your address bar and press Enter:

WaaSMedicService is the name of the registry key. You will see it in the left panel. Registry keys are a bit like folders. They can contain subkeys, which are like subfolders, and properties, which are like files.

Each registry key found under “Services” will have a property called “Start” that determines when or why the service will start.


Start can take a few different values:

  • 2 is “Auto”
  • 3 is “manual”
  • 4 is “Disabled”

Double-click the “Start” property in the right pane and change the value to 4, and then click “OK.”

double click

Suggestion: If you’ve used the Services app before, you may have noticed that some services are automatic, but are specifically designed to start “delayed.” The property that sets “Delayed” is called “DelayedAutoStart”. A value of 1 enables delayed autostart, while 0 disables delayed autostart.

Disable the use of our registry keys

One is called “Disable_WaaSMedicSvc.reg” and it will disable WaasMedicSvc (and WaaSMedicAgent.exe) completely. The other REG file is called “ReEnabled_WaaSMedicSvc.reg” and will return the service to its default value.


Just download the zip file, extract content anywhere and double click on “Disable_WaaSMedicSvc.reg”. You will get a warning about the dangers of applying registry keys – press “Yes”.
