Quick Note: Prerequisites and Initial Checks

Before you start troubleshooting, ensure you have the following:

  • Stable internet connection: Some fixes involve updating Windows or downloading files.
  • Administrator access: You may need to run commands or change system settings.
  • Check for Windows updates: Sometimes updates fix bugs causing high disk usage.
  • Close unnecessary applications: This helps isolate if WaasMedic Agent Exe is truly causing the problem.

Once these are confirmed, you can proceed with the solutions below.

Step 1: Restart Your Computer

Often, high disk usage problems occur temporarily. Restarting your PC clears temporary files and resets processes.

Why this helps: It refreshes system services and can stop any stuck WaasMedic Agent Exe activity.

  1. Click the Start button.
  2. Select Power and then Restart.
  3. Wait for your PC to reboot and check disk usage again.

Step 2: Run Windows Update Troubleshooter

Since WaasMedic Agent Exe is linked to Windows Update, running the troubleshooter can detect and fix related problems.

Why this helps: It automatically identifies issues with Windows Update components that may cause excessive disk usage.

  1. Press Win + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run beside it.
  4. Follow the on-screen instructions to complete the troubleshooter.
  5. Restart your computer if prompted.

Step 3: Disable WaasMedic Agent Service Temporarily

If the issue persists, you can temporarily stop the WaasMedic service to reduce disk usage. Be cautious as this service helps with Windows Update health.

Why this helps: Disabling the service stops the process using disk resources but only do this if other methods fail.

  1. Press Win + R, type services.msc, and press Enter.
  2. In the Services window, scroll down to find WaaSMedicSvc or Windows Update Medic Service.
  3. Right-click it and select Properties.
  4. In the Startup type dropdown, choose Disabled.
  5. Click Stop if the service is running, then click Apply and OK.
  6. Restart your computer and check if disk usage improves.

Note: This is a temporary fix. You should enable the service later to keep your system updated and secure.

Step 4: Check for Malware and Viruses

Malware can disguise itself as system processes or cause excessive resource usage. Running a full system scan can rule this out.

Why this helps: Removing malware can stop unwanted processes from abusing disk usage.

  1. Open Windows Security by pressing Win + I, then navigating to Privacy & Security > Windows Security.
  2. Click Virus & threat protection.
  3. Choose Quick scan or for thorough checking, select Full scan.
  4. Follow the instructions to remove any detected threats.
  5. Restart your PC afterward.

Step 5: Reset Windows Update Components

Sometimes, corrupted Windows Update files cause the WaasMedic service to misbehave. Resetting these components fixes such issues.

Why this helps: It clears and rebuilds update-related files and services, which can reduce high disk usage.

  1. Type cmd in the Start menu search.
  2. Right-click Command Prompt and select Run as administrator.
  3. In the command window, type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

After completing these commands, restart your computer and check if the disk usage has normalized.

Alternative Method: Adjust WaasMedic Agent Exe Priority

If you prefer not to disable the service, lowering the process priority can reduce its impact on disk usage.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Go to the Details tab.
  3. Find WaasMedicAgent.exe in the list.
  4. Right-click it and hover over Set priority.
  5. Select Below normal or Low.

This tells Windows to allocate fewer resources to the process, helping reduce disk usage without stopping it entirely.
