Impact: You might receive an error or files might intermittently fail to save or copy, especially to network shares. Originating KB URL: N/A Originating Build: N/A Resolved KB URL: https://support.microsoft.com/en-us/topic/5027231 Date Resolved: 2023-06-13T10:00:00-07:00 Vendor Message History: ======================= Published: 2023-06-20T20:32:01.997+00:00 ---------------------------------------- You might have intermittent issues saving, or copying, or attaching files using 32-bit apps which are large address aware (https://learn.microsoft.com/windows/win32/memory/memory-limits-for-windows-releases#memory-and-address-space-limits) and using the CopyFile API (https://learn.microsoft.com/windows/win32/api/winbase/nf-winbase-copyfile). Windows devices are more likely to be affected by this issue when using some commercial/enterprise security software which uses extended file attributes. We are not receiving reports that copying files using File Explorer is affected, but CopyFile API (https://learn.microsoft.com/windows/win32/api/winbase/nf-winbase-copyfile) used within apps might be affected. 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 comercial device. Note: Apps are not affected by this issue if they are 64-bit or 32-bit and NOT large address aware (https://learn.microsoft.com/windows/win32/memory/memory-limits-for-windows-releases#memory-and-address-space-limits). Workaround: To mitigate the issue, you can attempt to save or copy again. Since the issue is intermittent, it is likely to succeed on a subsequent try. Resolution: This issue was resolved in updates released June 13, 2023 (KB5027231 (https://support.microsoft.com/help/5027231)) and later. We recommend you install the latest security update for your device. It contains important improvements and issue resolutions, including this one.
