If you’ve installed the May 2022 Cumulative Update for Windows 11, you may have encountered issues with apps. Some apps may crash, fail to open, or experience other issues on affected devices.
Microsoft released cumulative updates for all supported versions of its Windows operating system on May 2022 Patch Day.
The official KB5013943 release notes for Windows 11 highlights two issues that affect some apps on some devices. Microsoft also updated the Windows 11 known issues list to reflect the issues.
The first issue was already present in preview update KB5012643, which Microsoft released in late April for Windows 11. Some .NET Framework 3.5 applications may not start, hang, or display other issues after installing the preview update. The same issue affects stable update KB5013943 for Windows 11, which Microsoft released on May 10, 2022 to the public.
After installing this update, some .NET Framework 3.5 applications may experience issues or fail to open. Affected applications use some optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.
According to Microsoft, the issue can be mitigated by running several commands from an elevated Command Prompt window:
dism /online /enable-feature /featurename:netfx3 /all
dism /online /enable-feature /featurename:WCF-HTTP-Activation
dism /online /enable-feature /featurename:WCF-NonHTTP-Activation
This re-enables .NET Framework 3.5 and Windows Communication Foundation on affected systems and should resolve the issue. Admins can also re-enable them in the Control Panel, but most may prefer the commands as they can be run quickly.
If the proposed mitigation does not resolve the issue, administrators can roll back the update by uninstalling it on affected devices. You can check out our guide on uninstalling Windows updates here, if you need help with that.
The second known issue that has been confirmed by Microsoft is for Windows devices with “some GPUs”. Microsoft is not specific in describing the problem.
Applications may “exit unexpectedly” and “intermittent issues that affect some applications that use Direct3D 9” may also be experienced on affected devices. Microsoft notes that the Windows Event Log may log the error in Windows Logs/Applications. The faulting module is d3d9on12.dll and the exception code is 0xc0000094.
Microsoft has performed a known issue restore on affected devices, which may take up to 24 hours. According to Microsoft, company-managed devices may require special Group Policy configurations to resolve the issue.
Now you: Did you experience any issues after installing the May 2022 Updates?
