Microsoft releases an emergency fix for Windows 11 following a bug that emerged after the November 11 update. The update KB5072753 addresses an issue that arose with patch KB5068966. This error caused Windows Update to repeatedly download and reinstall the same update even though it was already installed.
In short, bugs persist in Windows 11, even as Microsoft aims to improve the stability of its operating system. The Redmond company explains in its official documentation: “After installing the hot patch update of November 2025 KB5068966 on Windows 11 25H2, Windows Update may download and re-install the update again. This does not affect functionality. Only the update history will show the last installation.”
Microsoft Deploys an Emergency Fix After a Strange Bug in Windows 11
True, this bug among many in Windows 11 does not compromise the security or performance of PCs, but many administrators were perplexed by the situation. The logs showed identical entries, creating the impression of an unstable maintenance state.
The fix KB5072753 completely replaces the faulty update KB5068966. If you install this update, there is no need to apply the previous one, since this cumulative patch includes all security fixes and improvements. Microsoft notes that this out-of-cycle update does not require a PC restart, as hot patching allows corrections to be applied without shutting down the operating system.
Hot patching is one of the major innovations of Windows 11, although it remains less favored than Windows 10 and its millions of users, despite the end of support. This feature is now available for both the 25H2 and 24H2 versions of Windows 11, as well as Windows Server 2025.
Windows 11 Has Been Criticized for Its Numerous Bugs Since Its Launch
The benefits are clear: this mechanism allows security fixes to be received without restarting your PC. Overall, this is good news that greatly reduces downtime for critical servers, virtual machines, and sensitive workstations in professional settings.
As previously mentioned, this is not a new situation regarding bugs for Windows 11, which is losing market share to Linux distributions like Zorin OS 18. Earlier this week, Microsoft rolled out an emergency update for Windows 10 aimed at resolving installation failures of the November 2025 security patches.
Previously, the Redmond company had also fixed a bug that falsely displayed warnings about the end of support for PCs running Windows 10, which were still covered by extended updates. Many users had reported the appearance of false messages on the Windows Update settings page indicating that their version was no longer supported.
