Microsoft issues SECOND emergency out of band update for Windows 11 to address disastrous Patch Tuesday bugs

Microsoft's January 2026 Patch Tuesday updates for Windows 11 have caused significant user frustration, leading to two emergency out-of-band updates within a week to address critical issues. The latest emergency update, KB5078127, was released to fix problems that made applications like Outlook, OneDrive, and Dropbox inoperable after the January 13 updates. Initially, users were advised to uninstall the updates as a temporary fix. The first emergency update on January 17 aimed to resolve shutdown and hibernation failures for version 23H2 and issues with Remote Desktop sign-in, but it inadvertently caused further disruptions to essential applications. The Windows release health dashboard remains a key resource for users seeking updates on ongoing issues.

Microsoft releases KB5068781 — The first Windows 10 extended security update

Microsoft has released the KB5068781 update, which is the first extended security update for Windows 10 since the operating system reached its end of support last month. This update follows the final cumulative update on October 14, which ended bug fixes and free security updates for Windows 10. Extended security updates (ESU) are available for consumers and business customers for up to three years, depending on the account type. Consumers can enroll in the ESU program through payment, Microsoft reward points, or Windows Backup synchronization. In the European Economic Area, additional options include free access with a Microsoft account or payment for a local account. Business customers can utilize the ESU program for three years at a total cost of 0 per device. A bug has affected some devices' enrollment in the ESU program, prompting Microsoft to issue an emergency fix. Users can install the update via Settings and Windows Update. The update is mandatory and will automatically install, requiring a device restart. After installation, Windows 10 ESU will be upgraded to build 19045.6575, and Windows 10 Enterprise LTSC 2021 will be updated to build 19044.6575. The update primarily addresses a bug that incorrectly indicated Windows 10 LTSC devices had reached their end of support. It also includes security updates that fix 63 vulnerabilities, including one actively exploited elevation-of-privilege vulnerability, with no known issues reported.

Warnings Mount Over Windows Server Update Services Hacks

Concerns have increased regarding a critical vulnerability in Windows Server Update Services (WSUS), identified as CVE-2025-59287, which allows unauthenticated attackers to execute arbitrary code. This vulnerability arises from a legacy serialization mechanism within WSUS, which is no longer actively developed. The Cybersecurity and Infrastructure Security Agency (CISA) has added this vulnerability to its Known Exploited Vulnerabilities catalog, indicating its urgency. Cybersecurity firms have reported active exploitation attempts, with thousands of WSUS instances exposed to the internet. Attacks are primarily reconnaissance activities that could lead to broader network compromises. If an attacker compromises a single server, they could control the entire patch distribution system, enabling internal supply chain attacks and distributing malware disguised as legitimate Microsoft updates. Alerts have been issued by the Canadian Center for Cybersecurity and the Australian Cyber Security Centre regarding this global threat. Microsoft's initial patch on October 15 failed to fully resolve the issue, allowing attackers to exploit the vulnerability quickly. Attack vectors include exploiting the deserialization of AuthorizationCookie objects and unsafe deserialization via the ReportingWebService. The vulnerability is particularly concerning because WSUS is often neglected and should not be exposed to the internet.

Act Now — Microsoft Issues Emergency Windows Update As Attacks Begin

Microsoft has announced an emergency fix for a critical vulnerability, CVE-2025-59287, affecting Windows Server users, specifically within the Windows Server Update Service (WSUS). The Cybersecurity and Infrastructure Security Agency (CISA) has indicated that attacks exploiting this vulnerability are already occurring. The WSUS Server Role is not enabled by default, meaning only servers with this role activated are at risk unless the fix is applied. CISA has mandated that certain federal agencies address this issue within two weeks and advises organizations to follow Microsoft's guidance to prevent unauthorized remote code execution. Recommended steps include identifying vulnerable servers, applying the security update released on October 23, 2025, and rebooting WSUS servers post-installation. For those unable to update immediately, disabling the WSUS server role and blocking inbound traffic to ports 8530 and 8531 is advised.

Microsoft Confirms Emergency Update For Millions Of Windows Users

Microsoft's latest mandatory security update for Windows 11, KB5066835, has caused significant disruptions, including inoperable localhost connections and multiple installation failures. Users are experiencing issues with locally hosted applications, and the update has also affected certain Logitech peripherals and mouse and keyboard functionality in the Windows Recovery Environment (WinRE). Microsoft has acknowledged these problems and plans to release an emergency fix within 48 hours. A regression in the kernel-mode HTTP server (HTTP.sys) is responsible for the localhost connectivity issues, particularly impacting Internet Information Services (IIS). Users are advised against seeking online troubleshooting solutions, as they have proven ineffective, and some have found risky temporary workarounds.
