Microsoft's Buggy Start: January Patch Causes Chaos
18 Jan
Summary
- January security update caused login and shutdown issues.
- An out-of-band update was released on January 17th.
- Secure Launch devices impacted by shutdown and hibernation bugs.

Microsoft released its initial 2026 security update for Windows 11 on January 13th, but significant bugs emerged rapidly. Within four days, an out-of-band update was issued on January 17th to address critical problems impacting system stability and user access. The issues specifically included connection and authentication failures for remote connection applications across multiple Windows versions.
Furthermore, devices equipped with Secure Launch experienced failures in shutting down or hibernating. This particular bug exclusively affected Windows 11, version 23H2, indicating a targeted impact within the user base. The rapid deployment of an emergency patch underscores the severity of these identified flaws.
This recent incident marks another instance where a routine security patch introduced widespread problems, necessitating an out-of-band update. While these emergency patches were once uncommon, their increasing frequency raises concerns about the quality assurance process for Windows updates. Microsoft continues to address these emerging issues to ensure system reliability for its users.
