The SFC / scannow tool is 'disproportionate' by a silly error after updating the new Windows 10 version

Microsoft's default software repair tool is currently experiencing problems, and according to the initial diagnosis, the underlying cause stems from Windows Defender.

If you don't know, sfc / scannow is a command commonly used to run System File Checker. This command is responsible for replacing corrupted Windows files with another stored version.

1. Choose which antivirus software to install on Windows 10 / 8.1 / 7 and this is Microsoft's recommendation

In a somewhat confusing 'event', an error has caused System File Checker (SFC) to flag incorrectly for Windows Defender's PowerShell module files, assuming these files are corrupted.

It is noteworthy that the above silly error is said to only appear after users upgrade to the latest Windows 10 update, and at the same time can affect almost all Windows 10 versions, including May. 2019 Update and version 1607.

1. RASMAN service is suspended due to Windows 10 1903 update error

SFC has flagged newly updated files as inappropriate

Before the incident, Microsoft gave the following explanation:

The files used for Windows Defender's PowerShell module placed in the % windir% System32WindowsPowerShellv1.0 folderModulesDefender are part of the Windows image. These files are catalog-signed. However, the management component of Windows Defender now has an update channel in addition to the new band. This channel replaces the original files with updated versions that are signed by using the Microsoft certificate trusted by the Windows operating system. Because of this change, the SFC flagged incorrectly that the newly updated files were inappropriate '.

1. A new error on Windows 10 caused a significant slowdown in shutdown speed and a temporary fix

Thus while waiting for Microsoft to correct the error (the error correction process is being implemented), Windows 10 users should best ignore the SFC error messages for those files that are marked incorrectly. It is expected that this error will be thoroughly fixed in the next Windows update.
