Since waasmedicagent.exe is a Windows component, the user can’t disable it directly. Hence, the user has to change some registry values in order to get access.

There are two ways of changing the registry values. 

  • Use a third-party tool called Windows Update Blocker.
  • Use the Built-in Registry Editor. 

As third-party software applications can’t be considered safe, the user can go ahead with the following steps for Built-in Registry Editor:

  1. Click on Windows + R to open the Run Dialog box and type ‘regedit’ for opening the Registry Editor.
    Type ‘regedit’ to open the Registry Editor.
  1. Then paste the path given below after “Computer/” in the address bar to enter the folder of waasmedicagent.exe-


    Enter the WaasMedicSVC Folder in Registry Editor

    Select start option in Registry Editor
  1. After that, change its Value Data to 4 from 3. Then reboot your system after clicking on OK and confirming the changes.
    Change the value and click OK.
  1. Go to Services again, after the successful start of your system, and search Windows Update Media Service which is disabled now.
    Find the now Disabled Windows Update Medic Service.
  1. In order to re-enable, change the value data of Start again in the Registry Editor folder of WaaSMedicSVC. However, this time do the vice versa i.e., change it back to 3 and if the error still occurs, then try inserting 2 instead of 3.


Is WaaSMedicSVC a virus that is harmful to the system?

Some third-party software applications might detect ‘waasmedic agent exe‘ as a threat or virus. However, that can be a chance of this being an error of judgment. There are two ways that the virus creators can use to their advantage, and they are as follows:

  • They can create some third-party antivirus and program it in such a way that it will judge WaasMedicAgent.exe as a virus. So, when a user will disable this executable file, it allows them to exploit the security flaws of the user’s system.
  • That executable file can be malware because malware creators often use executable files to inject malware into a system.

Therefore, the users should never use any unknown third-party antivirus and rather rely on the popular ones, but if popular ones also mark that executable file as a threat or virus, then the users should confirm that executable file’s ownership. 

The file is not malware if it’s marked as © Microsoft Corporation. All rights reserved.

Is it alright to disable the WaasMedicAgent.exe?

Waasmedicagent.exe is an important component of the Windows update service, which helps in the restoration and protection of Windows update components. Even though the user can’t disable it directly by going to the Services option, they can still manage to do so , but that will result in errors during Windows updates.
