Threat Score
A persistent Windows 11 in-place upgrade bug is deleting 802.1X wired authentication policy files (C:\Windows\dot3svc\Policies) during upgrades (reported across 23H2→24H2 and 23H2→25H2), leaving enterprise workstations offline until policies are restored; admins should back up policy files or apply mitigations (connect to a non-802.1X port and run gpupdate, use SetupComplete scripts, or re-push settings via MECM) because Microsoft has not publicly acknowledged or issued a fix.
