Microsoft is investigating a phenomenon that appears to cause various applications to have problems saving, copying, or attaching files. The developers have already been able to narrow down the error to 32-bit applications that use functions of the CopyFile API and are “large address aware”, i.e. can handle files up to 4 gigabytes in size.
The analysts continue in the Windows Release Health Notesthat Windows devices are more likely to be affected if certain commercial or enterprise security software is used that uses extended file attributes.
Windows error: Microsoft Office affected
We haven’t received any reports that copying using File Explorer is affected, but apps using the CopyFile API are. Applications from the Microsoft Office suite such as Word or Excel would then show this behavior if they were in the 32-bit version. Users may then receive the “Document not saved” error message.
Microsoft employees estimate that end customers with Windows devices in the home or unmanaged environment are less likely to encounter the phenomenon. However, if you have the problem, you should simply try again to save or copy the file. Since the behavior occurs sporadically, the process works when trying again.
The Windows 10 and 11 operating systems are affected in versions 22H2 and 21H2. Microsoft is working on solving the problem and wants to distribute it with a future update.
On Wednesday of this week Microsoft released the May update previews for Windows. In it, the manufacturer has solved printer problems, among other things.
