This update contains the following two manifests that are occasionally updated by the Diagnostic Tracking Service:
telemetry.ASM-WindowsDefault.json
utc.app.json
The two files are marked as static files in the update. When an advanced user runs the System File Checker Tool (sfc.exe), the files are unintentionally flagged as corrupted. There is no impact or corruption on a device that is running this update, and this issue will be fixed in a later service update.
