If you are viewing this page on a Windows PC, you are already relying on several system processes to get you here. At the top is the Windows system kernel (ntoskrnl.exe) that allows software to communicate with your PC hardware. Lower level applications such as Chrome (chrom.exe) use the kernel to display pages like this one.
Unfortunately, not every application and system service is reliable. Bugs, vulnerabilities and high CPU usage are common and should be fixed with regular Windows updates. Ironically, Windows Update itself can cause high CPU and RAM usage through related services like haze medic† Here’s what you need to know.
What is the Waasmedic service on Windows?
The laundry medicine service (also known as the Windows Update Medic Service and Wasmedicagent.exe) is a background system service that handles part of the Windows Update process. Waasmedic is responsible for protecting Windows Update from being disabled or misused (for example, due to rogue malware infections).
If you (or anything else) try to disable Windows Update, the washing medic process will step in to stop it. If system processes related to Windows Update are disabled, wassmedic will restart them. You can’t easily disable it as it bypasses the built-in protection for Windows Update in Windows 10.
If you’re concerned about this process, don’t worry: it’s completely legit and part of the necessary components for your PC to run properly. It’s unlikely that the running laundry medic or Windows Update processes on your PC are anything but the real deal, but if you’re not sure, make sure you check for possible malware†
What causes the high usage of CPU, RAM and other system resources by Waasmedic?
Windows is unlikely to call this small executable for no good reason. If you see hazemedic (or Windows Update) reporting high CPU, RAM, or other high system resource usage in the Task Manager, it’s a sign that Windows Update is having issues and may require further investigation and troubleshooting.
This is because the Windows Update Medic Service (as it was officially called) is a service that monitors the “health” of the overall Windows Update service on your PC. If Windows Update encounters problems, hazemedic will try to fix it. It can restart Windows Update if it stops unexpectedly, for example.
Should hazemedic report high CPU usage in the Task Manager, it’s a sign that something is going on behind the scenes. A small increase is to be expected, but if you see high CPU usage over an extended period of time, you should check if Windows Update is working properly by following the steps below.
Most users may not see hazemedic appear at all in the Task Manager. If everything works, the process can only appear when an action (such as repairing Windows Update) is performed.
Troubleshooting Waasmedic on Windows
Windows Update is the focus of the laundry medic process. If you see hazemedic reporting high CPU usage or other issues, it is almost certainly related to a problem with Windows Update on your PC.
Fortunately, there are some general troubleshooting steps you can follow to resolve this. First check (initially) if Windows Update is working and if all available updates are installed. If you’re still having issues, you can use built-in tools to check the health of your system.
Check if Windows Update is working properly
To check if Windows Update is working properly, do the following:
- Right click on the Start menu and select Settings†
- In the Settings menu, select Update & Security † Windows Update† If Windows Update is working properly, Windows will check for available updates and prompt you to install them. To do this, follow any additional on-screen instructions.
- If Windows Update doesn’t work, right-click the Start menu and select Run†
- In the Run box, type services.mscand then select Okay to confirm.
- In the Services window, browse and search Windows Update and Windows Update Medic Service† If these services are not running, right click on each service and select Get started† Otherwise, right click on each service and select Restarting instead of.
- Once the Windows Update services are up and running, return to the Windows Update menu in Windows settings and check for new updates. If the system works, hazemedic should return to normal levels of system resource usage (usually extremely low).
Fix Windows with DISM and SFC
If you are unable to repair Windows Update, or if there is a problem that prevents you from restarting Windows Update system services, your Windows system files may be corrupted. Windows includes built-in tools called DISM and SFC to help you solve this problem, but you must use the Windows PowerShell to use them.
To recover your Windows system files, you need to do the following:
- First you need to open a new PowerShell window. Right click on the Start menu and select Windows PowerShell (administrator) to do this.
- In the new PowerShell window, type dism.exe /Online /Clean-image /Restorehealth and select the Enter key. Follow any additional on-screen instructions.
- After the DISM tool has cleaned your built-in Windows system image, you can use it to repair your Windows system files. To do this, type sfc /scannow and select Enter†
Wait for a while for the SFC scan to complete and restart your PC once it is complete. Windows automatically recovers any files that are damaged or missing. But if you’re still having issues, you might want to consider scanning for malware or reset windows completely to ensure that your Windows installation is stable and error-free.
Disable the Windows Update Medic service?
Windows Update is one of many protected system services in Windows 10. Unlike previous versions of Windows, you can’t prevent Windows Update from checking for or installing important updates. It is considered critical to the security of your PC that these updates are installed without additional interaction.
This means that you cannot completely disable the hazemedic service without using sketchy and unreliable software. Although there are third-party tools to disable it, we do not recommend that you try them as we cannot guarantee that they are safe to use.
Disabling Windows Update can also cause system instability and expose your PC to security vulnerabilities. However, you can temporary disable Windows Update for up to 35 days. This limits the use of system resources for hazemedic so that you can troubleshoot any problems with it.
Temporarily disable Windows Update
- To temporarily disable Windows Update (and reduce usage of hazemedic system resources), right-click the Start menu and select: Settings†
- In the Settings menu, select Update & Security † Windows Update † Advanced options†
- In the Advanced options menu, select how long you want to pause all updates with the Pause updates drop down menu. Any changes you make will take effect immediately.
Once Windows Update is temporarily disabled, all system processes related to Windows Update (including hazemedic) will remain inactive until the update resumption date has passed or until you manually re-enable Windows Update.
Protect your Windows 10 PC
If you are concerned about the Windows Update Medic Service (haasmedic) on your Windows PC, don’t panic. It is legitimate and is included as a way to protect Windows Update from interruptions. While you can use third-party tools to disable Windows Update, we don’t recommend doing so, although you can stop individual updates.
The haze medical service is there to help, but it doesn’t solve everything. If Windows Update doesn’t install new updates, some common troubleshooting steps can help you troubleshoot, especially if the updates crash. If all else fails, remember that you can wipe and reset Windows to restore your PC afterward.
