[Updated 2026-01-15: After further investigation, we concluded that this issue was not applicable to Windows 10, version 1607 (Windows 10 2016 LTSB edition). This version was removed from the "Affected platforms" section in this documentation.]
After installing the January 2026 Windows security update (KB5073722), credential prompt failures might occur in some remote connection applications. This includes remote desktop connections using the Windows App on Windows client devices, on Azure Virtual Desktop and Windows 365. The Windows App is affected by this issue on specific Windows builds and can experience sign-in failures.
Other remote connections and related applications may be similarly impacted.
Resolution: To address this issue, an out-of-band (OOB) update was released January 17, 2026, in the Microsoft Update Catalog.
If the OOB is not installed, one of the following connection options can be used as a temporary workaround:
- Use the Remote Desktop client for Windows to connect to Azure Virtual Desktop here (/previous-versions/remote-desktop-client/whats-new-windows?tabs=windows-msrdc-msi)
- Connect using the Windows App Web Client at windows.cloud.microsoft
Affected platforms:
- Client: Windows 11, version 25H2; Windows 11, version 24H2; Windows 11, version 23H2; Windows 10, version 22H2; Windows 10, version 21H2, Windows 10 Enterprise LTSC 2019
