Microsoft released an out-of-band (OOB) update yesterday to fix some Windows issues caused by last week’s monthly patching cycle on Patch Tuesday.
The January 2022 updates that shipped last week included security patches and a fix for Japanese text appearance issues in Windows 11 (KB5009566) and Windows 10 (KB5009543) — along with a secret payload of issues, including unexpected restarting of Domain Controllers and VPN connections using L2TP failing.
One of the major issues that came up during the week for IT admins included finding that Windows Server 2012 became stuck in a boot loop, while other versions suffered broken Windows VPN clients, and some hard drives appeared as RAW format (and unusable). Many IT Admins were forced to roll back the updates — leaving many servers vulnerable with none of last week’s security patches.
