Microsoft has just released an important emergency update for its Windows 10 operating system. This new update, KB5061768, fixes a critical problem introduced by a recent security patch. The problematic May 13, 2025 security update (KB5058379) caused unexpected system failures. Affected users were often forced to enter their BitLocker recovery keys to regain access. This fix arrives as Microsoft continues its regular Windows 10 update cycle this year. Windows 10 itself is fast approaching its official end-of-support date later in 2025. The emergency update specifically addresses issues on devices with certain Intel vPro processors.
The severe problem particularly impacted devices enabling Intel Trusted Execution Technology or TXT. These systems had 10th generation or newer Intel vPro processors installed inside them. After installing the May security update, the LSASS process would unexpectedly terminate. This critical failure of the Local Security Authority Subsystem Service triggered Windows Automatic Repair. This repair process then prompted users to enter their unique BitLocker recovery key. Regaining access to their computer systems absolutely required this specific BitLocker key entry. For many enterprise users, this issue resulted in a surge of increased support calls. It also created potential data access problems when recovery keys were not readily available. Microsoft acknowledged this as a known OS Security issue affecting its business customers.
The crucial emergency fix (KB5061768) is available now through several different distribution channels.
Home users can access this important update easily through the standard Windows Update service. It is also available for many business deployments, but not via Windows Server Update Services. System administrators needing wider deployment can download it from the Microsoft Update Catalog. This new update includes the latest servicing stack update, also known as an SSU. Microsoft now typically bundles these SSUs with its cumulative updates for better reliability. This practice helps improve the overall reliability of the entire Windows update installation process.
Important SSU prerequisites exist for offline OS image servicing and some WSUS deployments.
This recent emergency Windows 10 update comes with a very timely reminder from Microsoft. Support for the Windows 10 operating system is quickly nearing its official end date. After October 14, 2025 Microsoft will no longer provide any free software updates. This also means no more technical assistance or critical security fixes for Windows 10. While PCs running Windows 10 will continue to function, they will become more vulnerable. These systems will face increasing security threats without the benefit of regular patches. Microsoft therefore strongly recommends that all users transition to Windows 11 very soon. This BitLocker issue underscores the vital importance of timely OS security update installation. It also clearly highlights risks for organizations using unsupported operating system versions. Enterprises should accelerate Windows 11 migration or consider paid extended support options.
