Following installation of the July 2025 Windows security updates (KB5062557), there might be issues when using the Microsoft Changjie IME (input method editor) for Traditional Chinese.
This issue only affects devices where Traditional Chinese is a preferred or common language or input method, and specifically where Changjie IME is used. Reported symptoms include:
- inability to form or select words after typing the full composition (associate phrase window)
- spacebar or blank key not responding
- incorrect or distorted word outputs
- the conversion candidate window fails to display properly
Microsoft Changjie is an IME that is included in Windows and available in currently supported versions.
Workaround: Windows IME supports a compatibility setting that allows using the previous version of an IME instead. Employing this option should help resolve this issue.
To revert to old version of the Microsoft Changjie IME, follow these steps:
- Open the Language & region setting. This can be accomplished by opening the Settings app, selecting Time & Language, then Language & Regions. You can also open the start menu and type "language" and select the top result.
- If Traditional Chinese is used on this device, the Chinese (Traditional) option will appear near the top. Select the three dots next to Chinese (Traditional) to open a menu and select Language Options.
- Under Keyboards, select the three dots next to Microsoft Changjie and select Keyboard Options from the menu.
- Under Compatibility, set the "Use previous version of Microsoft Changjie" option to On. Then select OK.
Next steps: We are working on a resolution and will provide more information when it is available.
Affected platforms:
- Client: Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2; Windows 10, version 1809; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607

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

After installing updates released January 11, 2022 or later, apps using Microsoft .NET Framework to acquire or set Active Directory Forest Trust Information might fail, close, or you might receive an error from the app or Windows. You might also receive an access violation (0xc0000005) error. Note for developers: Affected apps use the System.DirectoryServices API.
Next Steps: This issue was resolved in the out-of-band update for the version of .NET Framework used by the app. Note: These out-of-band updates are not available from Windows Update and will not install automatically. To get the standalone package, search for the KB number for your version of Windows and .NET Framework in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog.
