The Windows Malicious Software Removal Tool (MRT) is a freeware app that Microsoft redistributes via the Windows Update service. The application can also be downloaded separately from Microsoft’s website. This tool is known to take a long time to complete scans and consumes system resources during those scans, so you might want to prevent Windows 10 from installing it. Here is how.

Here is How to Disable Malicious Software Removal Tool From Installing in Windows 10:

  • STEP 1: At first, open the Registry Editor. To do so, just press Win+R, type regedit.exe and press OK.

  • STEP 2: Go to the following Registry key

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT

    If you do not have this Registry key, then just create it. The MRT key might be missing.

  • STEP 3: Then, create a new 32-bit DWORD value named DontOfferThroughWUAU. Set its value data to 1.

  • STEP 4: Restart Windows 10.

    • If you had Microsoft Malicious Software Removal Tool installed in Windows 10, you can easily uninstall it now.

    wusa /uninstall /kb:890830 /quiet /norestart
