Windows 10 SFC /scannow Can’t Fix Corrupted Files After Update

Starting today, Windows 10 users are finding that the /sfc scannow feature is no longer working and that it states it found, but could not fix, corrupted Windows Defender PowerShell files.

The Windows System File Checker tool, commonly known as SFC, has a /scannow argument that will check the integrity of all protected Winodws system files and repair any issues that are found.

As of this morning, users in a wildersecurity.com thread have started reporting that when they run sfc /scannow, the program is stating that “Windows Resource Protection found corrupt files but was unable to fix some of them.” I too was able to reproduce this issue on a virtual machine with Windows Defender configured as the main antivirus program.
