KB5077796

Microsoft has released an out-of-band cumulative update, KB5077796, for Windows 10 version 22H2 (ESU). This update addresses login failures that occurred during Remote Desktop connections.

The patch resolves login crashes during Remote Desktop sessions that appeared after installing the January 2026 update KB5073724 (Build 19045.6809). It fixes an issue where users encountered credential request errors when trying to establish a Remote Desktop connection to Windows 365 and Azure Virtual Desktop services through the Windows App. Microsoft had previously confirmed the problem and recommended temporarily using the classic Remote Desktop client or the web version of the Windows App as a workaround.

Note: Update KB5077796 is available only for manual installation from the Microsoft Update Catalog.
