Solution 1: Scan your computer for malware

To help with WaasMedic.exe taking up too much of your computer’s resources, we suggest scanning for viruses first. This will allow you to identify and remove any malicious programs or scripts that are running on your device, which could be causing the issue.

To protect your computer from malware, you can employ the Windows Defender application. To get a more thorough scan, we advise getting a reliable antivirus program.

  • Once you’ve chosen the type of scan you want to run, click the “Scan now” button to begin. Depending on the size of your hard drive and the type of scan you’ve chosen, the scan may take several minutes or hours to complete. You can monitor the progress of the scan from the Windows Security app.

High CPU or disk usage of WaasMedic.exe may be caused by a misconfiguration or a conflict with a third-party antivirus program that is installed on your device. To determine if this is the case, consider disabling the antivirus temporarily to see if the issue resolves itself.

Solution 3: Pause Windows updates

Pausing updates on Windows can potentially fix this problem, as it doesn’t need to run WaasMedic.exe and use high CPU and disk resources.

Pausing Windows updates can help to reduce the amount of resources (CPU and disk) being used by WaasMedic.exe, which may help to resolve the problem.

Solution 4: Use the Disk Cleanup utility

The Disk Cleanup tool in Windows 10 is a handy feature that helps you get rid of unnecessary material from your computer. It eliminates temporary files, outdated drivers, and other unwanted items, allowing you to free up space and optimize system performance. This can be really helpful if you’re dealing with a large number of unnecessary files that can be slowing down the speed of your programs or even stopping them from running altogether.

Solution 5: Fix corrupted system files

Corrupt system files are a typical source of this error. Fortunately, Windows has a built-in utility, namely the System File Checker (or SFC scan) that can be utilized to restore all damaged files. This tool detects any missing or corrupted files and replaces them with the original versions.

You can use the SFC scan to bring back all possibly corrupt or missing system files on your device, which may help to repair the high CPU and disk usage caused by WaasMedic.exe.

How to use the System File Checker (SFC scan) to bring back corrupt or missing system files in Windows 11

If you’re ever having trouble with your Windows 11 computer and you’re not sure what to do, you can try using the Windows File Checker (SFC) scan. This scan will try to find all the possible corrupt or missing system files on your computer, and if it finds any, it will help you fix them.

To use the SFC scan, first open the Windows File Checker by clicking the ‘Start‘ button, typing ‘filechecker.exe‘ in the search box, and pressing enter.

In the window that opens, click the ‘Scan‘ tab, and then click the ‘Start Scan‘ button.

Once the scan is started, the computer will start scanning your hard drive for any possible corrupt or missing system files. This process can take a while, so be patient. If the scan finds any corrupt or missing system files, it will display them in the window that opens.

If you want to fix any of the problems that the SFC scan has found, you can do so by clicking on the ‘Fix’ button. This will try to fix the corruption or missing system files, and if it succeeds, the computer will restart automatically.

If you need help with any of the steps in this guide, be sure to consult the help files that are included with the Windows File Checker. These files can be found in the ‘Support’ folder on your computer, and they will provide you with more information about using the SFC scan.

Solution 6: Update Windows to the latest version

Upgrading your operating system could help address any underlying issues, like the WaasMedic.exe process using up a lot of your resources and your computer running slowly. Get the most current version of Windows to see if that solves the issue.

Solution 7: Disable the WaasMedic service (Last Resort)

If the methods mentioned above do not work, you can try to manually turn off WaasMedic.exe by making some changes to the settings in your computer’s registry. This may stop Windows Update from working, so be cautious when making these changes.


Once you have successfully blocked the WaasMedic.exe process from initiating, restart your device to make sure the service isn’t initiated. When your computer restarts, you can keep an eye on your CPU and hard drive utilization to decide if this approach worked.

Solution 8: Check For Windows Update

Keeping your Windows computer up-to-date is an important part of maintaining its security. Windows Update makes it easy to keep your system secure by providing the latest security and bug fixes. To check for updates, go to the Start menu and click on Check for Updates. If there are any available, Windows will show you a list of the updates and ask if you would like to install them. Alternatively, you can also choose to have updates installed automatically at a designated time.

Below are the steps you can follow to clear the Software Distribution Folder in Windows 11.

How to Clear Software Distribution Folder in Windows

Windows 11 uses a folder called the ‘Software Distribution’ folder to temporarily store files related to updates.

This will delete all of the files in the Software Distribution folder.

Finally, you will need to start the Windows Update service back up. To do this, type the following command and press Enter:

net start wuauserv

Your computer should now be running more smoothly.
