Microsoft outs Windows 11/10 KB5077744, KB5077797 emergency updates for manual downloading

This past week, Microsoft released the first Patch Tuesday updates of 2026 on Windows 11 and 10 under KB5074109, KB5073455 and KB5073724, respectively. As it happens often, the new security updates also caused issues as Microsoft confirmed shutdown and hibernation issues, as well as remote desktop connection problems following the updates.

These are major breaking problems and as such Microsoft this weekend released emergency out-of-band (OOB) updates to fix them. The updates are out for both Windows 11 and Windows 10 as the RD connection bug affects many Windows editions across 10 and 11.

They are available under KB5077744 for Windows 11 25H2, 24H2, KB5077797 on Windows 11 23H2, KB5077796 and KB5077795 on Windows 10. The changelog is given below:

• [Remote Desktop] Fixed: After installing the January 2026 Windows security update (KB5074109), some users experienced sign-in failures during Remote Desktop connections. This issue affected authentication steps for different Remote Desktop applications on Windows such as the Windows App.

• [Power & Battery] Fixed: Some devices with Secure Launch enabled restart instead of shutting down or entering hibernation.

   

These OOB updates are only available for manual downloading. Head over to the official Microsoft support articles on instructions on how to avail them from the Update Catalog: KB5077744 / KB5077797 / KB5077796 / KB5077795.
