PHYSIX OBSERVATION

Routing the patch through the app store instead of system updates exposes a blind spot in how Windows 11 built-in apps distribute security fixes: users assume an up-to-date system means they are safe, while Paint is in fact left unprotected. Microsoft has neither clarified whether the version number is a typo nor explained why the Store fails to push the update, and this vague handling will erode users' trust in automatic updates.
