The Start menu, Windows search, and Universal Windows Platform (UWP) apps might not work as expected or might have issues opening. Affected Windows devices might have damaged registry keys or data which might affect apps using Microsoft Office APIs to integrate with Windows, Microsoft Office, or Microsoft Outlook or Outlook Calendar. An example of an app affected by this issue is ClickShare. The underlying Issue is not caused by the installation of an update to Windows and might be exposed by an update to an affected app.

To mitigate this issue, you can uninstall apps which integrate with Windows, Microsoft Office, Microsoft Outlook or Outlook Calendar. Updates to affected apps or guidance from the developer of the app might also be available. If you are using ClickShare by Barco, please see Symptom: Start Menu and other shell components fail when Apps including Barco's ClickShare access Office APIs and Unresponsive Windows taskbar or user shell folder permissions issues with ClickShare App Calendar integration.

We are presently investigating and will provide additional information as it becomes available.

You might have intermittent issues saving, copying, or attaching files using 32-bit apps, which are large address aware and using the CopyFile API. Windows devices are more likely to be affected by this issue when using some commercial or enterprise security software that uses extended file attributes. Microsoft Office apps, such as Microsoft Word or Microsoft Excel are only affected when using 32-bit versions and you might receive the error, "Document not saved."

This issue is unlikely to be experienced by consumers using Windows devices in their home or on non-managed commercial devices. Apps are not affected by this issue if they are 64-bit or 32-bit and NOT large address aware.
