Issue details

January 2026

Some devices might fail to shut down or hibernate

Updated 2026-01-30: The investigation determined that Secure Launch-capable PCs with Virtual Secure Mode enabled are also impacted by this issue. We plan to resolve this issue in a future Windows update.

Updated 2026-01-24: The solution for devices with Secure Launch is now available via the Windows Update release channel.

Updated 2026-01-23: We are investigating reports that some devices are still impacted after installing the out-of-band update.

After installing the January 13, 2026, Windows security update (KB5073455) for Windows 11, version 23H2, some PCs with Secure Launch are unable to shut down or enter hibernation. Instead, the device restarts. Secure Launch uses virtualization-based security to protect the system from firmware-level threats during startup. KB5073455 is only offered for Enterprise and IoT editions of Windows 11, versions 23H2.

In addition, some Secure Launch-capable PCs with Virtual Secure Mode (VSM) enabled can experience this issue after installing Windows updates released on or after January 13, 2026 (KB5073455). This issue does not affect devices with AMD or ARM64 processors and is limited to the affected platforms listed below.

Resolution:

A solution for devices with Secure Launch is included in an out-of-band (OOB) update, released January 17, 2026 (KB5077797). Please note that this solution does not resolve the issue for Secure Launch-capable devices with VSM enabled.

KB5077797 is only available via the Microsoft Update Catalog, however, the same solution is included in the out-of-band update released on January 24, 2026 (KB5078132), which is available via Windows Update. If you have turned on Get the latest updates as soon as they're available in Windows Update settings (Settings > Windows Update), you will automatically receive this update. If the toggle is off on your device, you can install the update manually by going to Settings > Windows Update and selecting Download & install. Note that KB5078132 will show up in Windows Update only if you have installed one of the updates released in January that caused this issue.

We recommend using Windows Update to install this update. This OOB update is cumulative and includes all protections and improvements from the January 2026 Windows security update released January 13, 2026, and from the OOB update released January 17, 2026. We recommend installing the latest update for your device, as it contains important improvements and issue resolutions, including this one.

Next steps: We plan to release a solution for Secure Launch-capable PCs with VSM enabled in a future Windows update. We will provide more information when it is available.

Affected platforms:

• ​Client: Windows 11, version 23H2; Windows 10, version 22H2; Windows 10 Enterprise LTSC 2021; Windows 10 Enterprise LTSC 2019
• ​Server: None

Updated 2026-01-24: This message was updated to reflect the availability of a new Windows out-of-band update that addresses this issue and is available via the Windows Update release channel.

After installing the January 2026 Windows security update (KB5073455), 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:

Updated 1/24:

A new out-of-band (OOB) update was released on January 24, 2026. It can be found as KB5078132. If you have turned on Get the latest updates as soon as they're available in Windows Update settings (Settings > Windows Update), you will automatically receive this update. If the toggle is off on your device, you can install the update manually by going to Settings > Windows Update and selecting Download & install. Note that this update will show up in Windows Update only if you have installed one of the updates released in January that caused this issue.

We recommend using Windows Update to install this update. This OOB update is cumulative and includes all protections and improvements from the January 2026 Windows security update released January 13, 2026 and from the OOB update released January 17, 2026. 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.

As always, we recommend you install the latest update for your device as it contains important improvements and issue resolutions including this one. 

Updated 1/17:

This issue was originally addressed in an out-of-band (OOB) update released January 17, 2026, in the Microsoft Update Catalog. It can be found as KB5077797. For additional guidance, see How to download updates from 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
• ​Server: Windows Server 2025; Windows Server 2022; Windows Server 2019

Apps might become unresponsive when saving files to cloud-backed storage

After installing Windows updates released on or after January 13, 2026 (KB5073455), some applications might become unresponsive or experience unexpected errors when opening files from or saving files to cloud-backed storage, such as OneDrive or Dropbox.

For example, in some configurations of Outlook that store PST files on OneDrive, Outlook might become unresponsive and fail to reopen unless its process is terminated in Task Manager, or the system is restarted. In addition, sent emails might not appear in the Sent Items folder, and previously downloaded emails might be downloaded again. The affected Outlook configurations primarily involve classic Outlook, which is commonly tied to enterprise licensing and is not included with most home installations of Windows. To check your Outlook configuration, see Feature comparison between new Outlook and classic Outlook.

Resolution:

This issue is resolved in the out-of-band (OOB) update released on January 24, 2026, (KB5078132), and updates released after this date.

If you have turned on Get the latest updates as soon as they're available in Windows Update settings (Settings > Windows Update), you will automatically receive this update. If the toggle is off on your device, you can install the update manually by going to Settings > Windows Update and selecting Download & Install. Note that this update will show up in Windows Update only if you have installed one of the updates released in January that caused this issue.

We recommend installing the latest update for your device, as it contains important improvements and issue resolutions, including this one.

For devices that have not yet installed the OOB update, there is an optional workaround for Outlook-specific scenarios. Moving the Outlook PST files out of OneDrive should resolve this issue. For guidance, please see documentation at How to remove an Outlook .pst data file from OneDrive. In addition, email accounts can still be accessed via webmail, if supported by your email provider. 

Affected platforms:

• ​Client: Windows 11, version 25H2; Windows 11, version 24H2; Windows 11, version 23H2; Windows 10, version 22H2; Windows 10 Enterprise LTSC 2021; Windows 10 Enterprise LTSC 2019
• ​Server: Windows Server 2025; Windows Server, version 23H2; Windows Server 2022; Windows Server 2019

Parental consent may not show for some browser versions with web filtering on

Certain laws require Microsoft to protect children from harmful and illegal content on the internet. Microsoft is committed to creating tools for parents and guardians to help them in guiding their children’s digital experiences and protect them from harmful and illegal online content.

One of the available tools is web filtering, which lets a parent or guardian filter websites. Currently, Microsoft Edge is the only supported browser that provides this functionality within Microsoft Family Safety, allowing Edge to be used by default on the child’s device after web filtering is enabled. Once web filtering is enabled, a parent or guardian needs to approve other unsupported browsers (any browser other than Edge) before they can be used. This helps parents understand that different settings apply to other browsers when it comes to blocking inappropriate websites and filtering search results for their children.

The blocking behavior continues to work for unsupported browsers, however, when unsupported browsers update to a new version, the latest version of the browser cannot be blocked until we add it to the block list. Microsoft is currently adding the latest versions of unsupported browsers, to the block list. As a result, some browsers may temporarily appear unblocked during this update process. We're actively working to ensure all latest versions of browsers are blocked, reinforcing our commitment to parents and guardians.

As Microsoft continues to update the block list, we’ve received reports of a new issue affecting Google Chrome and some browsers. When children try to open these browsers, they shut down unexpectedly. However, the standard workflow is to prompt a parental approval message stating, “You’ll need to ask to use this app”. Once the approval is consented, the browser operates as intended. This issue is only observed when the Activity reporting feature is turned off.

Workaround: The browser shutdown issue can be temporarily mitigated by turning on Activity reporting under Windows settings in Family Safety. Parents will then be able to receive approval requests as expected.

Resolution:

• ​Temporary access to unsupported browsers: As of June 25, 2025, Microsoft included the latest versions of unsupported browsers into the Family Safety’s feature, and they are now blocked as intended. However, new versions of unsupported browsers released after this date might temporarily appear unblocked. This temporary gap will be resolved in the future, and this documentation will be updated to inform you when the full resolution is available.
• ​Missing parental consent prompt: Fixed in the July non-security preview update (KB5062663), released July 22, 2025. The fix is gradually rolling out and will be automatically enabled on devices with KB5062663 installed or later updates.

Affected platforms:

• ​Client: Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2
• ​Server: None
