A Windows 11 security patch released on January 13, 2026 caused shutdown, sleep, and remote access failures instead of fixing issues.
The shutdown bug mainly affected Windows 11 23H2 Enterprise and IoT systems, while remote desktop issues impacted a wider range of Windows versions.
Microsoft rolled out an emergency update within four days, raising concerns about update testing as such quick fixes become more common.
What was supposed to be a normal security update quickly became a problem for Microsoft and Windows users. On January 13, 2026, Microsoft released a Windows 11 update to fix security issues, but it ended up causing new problems instead. Many users soon reported that their computers would not shut down properly or that remote connections stopped working. Because of these issues, Microsoft moved quickly and released an emergency fix within a few days. Some of the worst problems affected certain business versions of Windows 11, but other users were impacted as well. This situation has raised new questions about how carefully updates are tested before they are released.
SurveyMicrosoft released an update for Windows 11 on January 13, 2026, and it was supposed to protect users from known threats. Instead, it led to new problems that disrupted normal computer use. Soon after the update went live, both companies and everyday users noticed strange behaviour, especially when shutting down computers or working remotely. However, Microsoft moved fast to respond, as the company released an emergency fix in just four days.
One of the biggest problems with the latest bug was that it was restricting computers from shutting down or entering sleep mode properly. Microsoft later confirmed that this issue only affected Windows 11 version 23H2. Even then, it was limited to Enterprise and IoT editions, mostly on systems where Secure Launch was enabled. This made the problem especially serious for businesses that need reliable systems.
Another issue caused by the update involved remote access. Many users found that remote desktop connections no longer worked. This problem affected more systems than the shutdown issue. It included newer versions of Windows 11, supported versions of Windows 10, and even Windows Server 2025. For users who rely on remote work, this episode was a major disruption.
Microsoft released an emergency update on January 17, 2026 to fix both problems. The company confirmed that it had identified the issues after users meant to improve security ended up causing unexpected failures.
Microsoft further provided more details on January 18, clearly stating that the shutdown and sleep issue was limited to Windows 11 version 23H2. This helped clear up confusion for users running other versions of Windows.

Although Microsoft acted quickly, the situation points to a larger issue. Emergency updates are happening more often, which suggests that some problems are slipping through before updates reach users. For now, Microsoft recommends that affected users install the emergency fix to get their systems back to normal.
