Is the WaasMedic agent eating up a lot of your resources and making your computer slow? This is not any malware or virus. WassMedic or Windows Update Medic Service is a legitimate process that runs continuously in the background, tracking and fixing corrupted Windows Update components on your system. Don’t worry. Just enact these easy solutions to fix the issue on your computer.
Fix 1 – Using the Registry Editor
You have to turn off the startup of the WassMedic Agent.
Step 1 –
1. At first, tap the Windows key and the R key at the same time.

a. Once you have opened the Registry Editor, you will need to click on the “File” and then click on “Export“.
b. Save the backup in a secure place.
If anything goes wrong, you can easily restore the registry back to the original level.
3. Once the Registry Editor terminal appears, navigate to this location-

5. Then, scroll down and double click on the “Start” key to edit it.
6. Finally, set the value to “4“.
7. Then, click on “OK” to save this change.
This will disable the service on your computer. Now, proceed to the second step.

6. Then, right-click on the task and click on “Disable” to disable the policy on your computer.
(Example – In this computer, there is a task called ‘PerformRemediation‘. So, we have disabled it. )
Once you have done all these, close the Task Scheduler on your computer. Then, a simple restart of your device and WaaSMedic won’t run on your device again.
Fix 3 – Use Windows Update Blocker (Wub)
You can use the Windows Update Blocker (WUB) to block particularly the Windows Update Medic Service.

Otherwise, run the “Wub” application if your machine is running on a 32-bit OS.
5. After opening the Windows Update Blocker screen, click on “Menu“.
6. Then, click on “Windows Services” from the drop-down list.
7. Now, scroll down through the services list, double click on the “Windows Update Medic Service“.

15. Then, click on “Apply” to apply these changes.
WaasMedic Agent won’t be using a huge amount of resources anymore. This should have fixed your computer.
