About this tag
The tag 'update 16992' refers to Windows 10 Home build 16992, an early preview version from the Windows Insider Program. Users have reported performance issues with this build, particularly involving the Antimalware Service Executable process. In this build, the antimalware service can spike CPU usage during large file operations, such as copying many files, causing system slowdowns and reduced transfer speeds.

Discussions focus on troubleshooting this behavior and seeking solutions for the high resource consumption.
