Issue: Attempt to update Windows Defender manually via the control panel results in blocks.
Symptoms: Content cannot be downloaded or downloaded content fails to be applied.
Cause: The typical approach to updating Windows Defender is via Windows Updates. Traditionally updates and patches are managed by the system administrator thus our Trusted Updater does not include rules for a manual update.
Solution: If the system administrator wishes to allow end users to manually update Windows Defender, then approve msascui.exe by its hash.
