Microsoft has issued an urgent patch to address critical bugs that plagued its latest security update for Windows 11. The January 2026 update was intended to provide improved security features, but it inadvertently introduced issues with shutdown and hibernation functionality on certain devices.
The problem arose specifically for users employing the Secure Launch feature, a security measure designed to protect against firmware-level attacks during startup. Unfortunately, this update rendered some Windows 11 devices unable to shut down or enter hibernation mode, forcing users to rely on forced restarts.
In related news, Microsoft has also restored remote login functionality for both Windows 10 and Windows 11 users. The company attributed the issue to credential prompt failures in affected devices.
Further complications have surfaced with some users still experiencing blank screens or Outlook Classic crashing after installing the latest update. This is not the first time Microsoft has had to intervene; an emergency fix was issued last October to address a separate Windows 11 issue related to the Windows Recovery Environment.
In response, Microsoft has extended its support for older versions of Windows by offering Extended Security Updates, allowing users to continue receiving security patches and updates on their current operating system until further notice.
