After installing the January 2026 Windows security update (KB5073457), 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. It can be found as KB5077800.
If you have not yet deployed the January 2026 Windows security update and your IT environment includes the affected applications and features, we recommend applying this OOB update instead. For additional guidance, see How to download updates from the Microsoft Update Catalog. As always, we recommend you install the latest update for your device as it contains important improvements and issue resolutions including this one.
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
- Server: Windows Server 2025; Windows Server 2022; Windows Server 2019

Windows Server 2022 and Server 2019 unexpectedly upgraded to Windows Server 2025

Windows Server 2025 is intended to be offered as an Optional upgrade in Windows Update settings for devices running Windows Server 2019 and Windows Server 2022. Two scenarios were observed in certain environments:
- Some devices upgraded automatically to Windows Server 2025 (KB5044284). This was observed in environments that use third-party products to manage the update of clients and servers. Please verify whether third-party update software in your environment is configured not to deploy feature updates. This scenario has been mitigated.
- An upgrade to Windows Server 2025 was offered via a message in a banner displayed on the device’s Windows Update page, under Settings. This message is intended for organizations that want to execute an in-place upgrade. This scenario has already been resolved.
The Windows Server 2025 feature update was released as an Optional update under the Upgrade Classification: “DeploymentAction=OptionalInstallation”. Feature update metadata must be interpreted as Optional and not Recommended by patch management tools.
We advise organizations to use Microsoft-recommended methods to deploy Windows Server feature updates.
Next steps: Microsoft is working with third-party providers to streamline best practices and recommended procedures. As an interim measure, Microsoft has also temporarily paused the upgrade offer via the Windows Update settings panel. We estimate it will be available in the first half of 2025. All other upgrading methods to install Windows Server 2025 are still available through the usual channels.
Once the offer via Windows Update resumes, IT administrators will be able to control the feature update offer banner by setting the target version to “hold” in the Group Policy “Select the target Feature Update version.” To learn how to manage feature updates via this group policy, see Manage Feature Updates with Group Policy on Windows Server.
Note: The Windows Server 2025 feature update was made available on November 1, 2024, as KB5044284, which was the same KB number used for Windows 11, version 24H2. This is the KB numbering for both client and server Windows updates. Future updates released for Windows Server 2025 and Windows 11, version 24H2 will share the same KB numbers, but will have different release note sites and links.
Affected platforms:
- Client: None
- Server: Windows Server 2025; Windows Server 2022; Windows Server 2019
