This MiniTool guide provides comprehensive information on the Microsoft Windows Malicious Software Removal Tool (MSRT), covering its purpose, download, execution, uninstallation, and updates on Windows 10/11.

Understanding the Windows Malicious Software Removal Tool

While familiar with Windows Defender Antivirus, many overlook the MSRT—a free, Microsoft-provided malware removal tool. A top-tier free malware solution, it's compatible with:

• Windows 11
• Windows 10
• Windows Server 2019
• Windows Server 2016
• Windows 8.1
• Windows Server 2012 R2
• Windows Server 2012
• Windows Server 2008 R2
• Windows 7
• Windows Server 2008

Microsoft regularly updates the MSRT via Windows Update. However, direct downloads are also available from the Microsoft Download Center and Microsoft Update Catalog.

Downloading and Running the MSRT

Three methods exist for obtaining the MSRT:

Method 1: Windows Update

The simplest approach is via Windows Update. Enabling Automatic Updates ensures you always have the latest version. Navigate to Start > Settings > Windows Update (Windows 11) or Start > Settings > Update & security > Windows Update (Windows 10) to check for and install updates. An example of an MSRT x64 update is shown below:

The MSRT automatically scans upon download. Subsequent scans run quietly unless malware is detected, prompting a notification upon administrator login.

Method 2: Microsoft Download Center

Download 32-bit or 64-bit versions directly from the Microsoft Download Center (links provided below, remember to check your Windows version). The download is a direct executable, requiring administrator privileges to run.

Method 3: Microsoft Update Catalog

Offline installers are available in the Microsoft Update Catalog. Search using the KB number (provided in the original article) to find and download the appropriate version.

Universal MSRT Execution

To run the MSRT at any time:

1. Press Windows R.
2. Type MRT and press Enter. Confirm User Account Control if prompted.
3. Click Next.
4. Select a scan type and click Next.

Updating the MSRT

Automatic Updates handle updates if enabled. Otherwise, download the latest version from the Download Center or Update Catalog.

Uninstalling the MSRT

The MSRT doesn't use an installer; it creates a temporary directory (usually C:\Windows\System32) automatically deleted upon exit or reboot. Manual deletion is safe if automatic removal fails.
