Windows 11 Update 2026 Stops Computers from Shutting Down Properly

Microsoft released its first security update of 2026 for Windows 11 on January 13th, but it was only four days later that an emergency out-of-band update was issued to address a critical bug introduced by the initial patch. The update was causing systems running on Windows 11 23H2, particularly those in the Enterprise and IoT editions, to malfunction. Specifically, it was preventing computers from shutting down or hibernating properly, as well as making it difficult for users to log in via remote desktop. Despite its limited impact, this is not Microsoft’s first experience with an out-of-band update due to a problematic patch. The company has faced similar issues in the past and has had to act swiftly to address these problems and ensure the stability of its operating system. The full extent of the bug’s impact is still being assessed, but it highlights the importance of timely and thorough testing before releasing updates to users.
