KB890830 update Windows Malicious Software Removal Tool 5.92 - Aug. 10


Windows Malicious Software Removal Tool (MSRT) 5.92 helps remove malicious software from computers running Windows 10, Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, or Windows Server 2008.

Microsoft generally releases MSRT monthly as part of Windows Update or as the standalone tool. Use this tool to find and remove specific prevalent threats and reverse the changes they have made (see covered threats). For comprehensive malware detection and removal, consider using Microsoft Safety Scanner.

This article contains information about how the tool differs from an antivirus or antimalware product, how you can download and run the tool, what happens when the tool finds malware, and tool release information. It also includes information for the administrators and advanced users, including information about supported command-line switches.

Note In compliance with the Microsoft Support Lifecycle policy, MSRT is no longer supported on Windows Vista and older platforms. For more information, go to Microsoft Support Lifecycle.

While other systems, for example my working OS Windows 8.1, have received today the Tuesday monthly update, Windows 11 got only this one. Apparently the security updates are being delivered out of common schedule, they are integrated in Dev/Beta updates. Until release...
