Microsoft has released an out-of-band update for Windows 11 users running the 24H2 or 25H2 builds, which includes important security patches and fixes for previous issues. The cumulative update specifically resolves a sign-in failure problem related to Remote Desktop that some users encountered after installing the January 2026 security update (KB5074109). This update also updates various AI features within Windows, including Image Search, Content Extraction, Semantic Analysis, and Settings Model, bringing them to version 1.2511.1224.0, as well as including a servicing stack update called KB5071142 for smoother background updates. Some users have reported a missing or invisible password icon on the lock screen sign-in panel after installing certain subsequent updates, but this issue appears to primarily affect enterprise and managed IT settings.

Windows 11 KB5077795 (OS Build 17763.8280) Out-of-band released

Microsoft just released update KB5077744 for Windows 11 users running either the 24H2 or 25H2 builds. This cumulative out-of-band update brings several fixes.

It includes important security patches, some tweaks from earlier releases to improve things overall, and specifically tackles an issue that cropped up previously. People who want more details about different kinds of Windows updates can look into resources like the official guide on monthly updates or learn about SSUs directly via their dedicated documentation page (link provided).

If you're curious about how this release is performing in terms of user feedback and known issues, there are dashboards specifically for tracking update health, definitely worth a glance if you keep your system updated.

One significant win from this new version is the correction related to Remote Desktop. After installing Microsoft's January 2026 security update (KB5074109), some users experienced difficulties connecting. This latest cumulative package appears to have resolved that specific sign-in failure problem, hopefully clearing things up for those using various Remote Desktop apps.

If your system is already running older builds like earlier versions of 25H2 or previous stable releases, it shouldn't need a full reinstall just to install this update. The system should handle pulling down and installing the necessary newer bits automatically.

There's another change worth noting: various AI features within Windows have been updated together (Image Search, Content Extraction, Semantic Analysis, and Settings Model). They all seem to be at version 1.2511.1224.0 now. This update also includes a servicing stack update called KB5071142.

That servicing stack part is crucial for keeping updates running smoothly in the background. Think of it as ensuring Windows' internal update machinery works properly; these changes help that process go more seamlessly without you needing to worry about it much.

But there's one hiccup reported by some users: a missing or invisible password icon on the lock screen sign-in panel after installing certain subsequent updates (especially KB5074109, but possibly others too). This seems to be primarily impacting enterprise and managed IT settings rather than typical personal devices running Windows Home or Pro.

If you're seeing the problem yourself, there's an emergency workaround called KIR that might help. For people using company-managed systems, tech admins can likely resolve things by installing a specific Group Policy setting named "Windows 11 24H2, Windows 11 25H2, and Windows Server 2025 KB5072033 251202_18051 Known Issue Rollback." Once applied, this policy will need to be configured properly, followed by a system restart, but it might temporarily disable the specific update causing the problem.
