General Sentiment

Little community discussion targets KB5126653 itself. Sibling update KB5127648 (24H2/25H2/26H2) has drawn complaints on Reddit and BleepingComputer, including broken WPA2-Enterprise 802.1x Wi-Fi authentication, boot failures on some 25H2 devices, and freezes. Those reports do not cover 23H2 directly, and some admins praised the security coverage, but the sibling's problems suggest caution.
