Windows 11 Buggy Update Causes Shutdowns, Crashes, and Boot Issues

Microsoft has issued a second out-of-band fix for its January 2026 Windows 11 update, addressing issues with OneDrive and Dropbox crashes that were affecting some users. The initial update was meant to bring security patches and improvements to the operating system, but it instead brought a wave of problems, including shutdowns on Enterprise and IoT editions of Windows 11 version 23H2. The first batch of complaints emerged shortly after the update’s release, with reports of machines shutting down unexpectedly in some cases. In response, Microsoft quickly issued an emergency fix to address the issue. However, just over a week later, the company has been forced to release another out-of-band patch to rectify problems with cloud storage services like OneDrive and Dropbox. It appears that the January 2026 security update has caused issues beyond just shutdowns, with some users reporting boot failures on their Windows 11 machines. Microsoft is currently investigating these incidents, which could be related to the same update that triggered the initial wave of complaints. The company’s response to this week’s update-related issues serves as a reminder of the challenges and risks involved in updating complex software like Windows 11.
