Windows 10/11: Known issues (May 2023)

Windows[German]In the last few weeks, various bugs (partly due to updates but also during development) have slipped into Windows 10 and 11versions. For example, there are issues when copying files under Windows 10 and Windows 11 – the operation can fail. Furthermore, there are problems with the Windows search, the Start menu and opening apps, since January, that has been mitigated. Microsoft has acknowledged the issues and partially corrected them. For example, the problems with the language recognition (Chinese, Japanese) have been fixed via update. I summarize the points below.


File operations (copy, save) fail

In Windows 10 and Windows 11, there are temporary problems with file operations such as copying or saving files that can fail. Microsoft has confirmed this issue as of May 24, 2022 in the post Saving or copying files might intermittently fail and writes:

Saving, copying, or appending files with 32-bit applications that consider large addresses and use the CopyFile API can occasionally cause problems.

The likelihood of systems being affected by this issue is said to be high when using commercial/enterprise security software that uses the extended file attributes. Copying files in File Explorer, on the other hand, does not appear to be affected. But the CopyFile API used in applications could be affected by this issue.

Microsoft Office applications like Microsoft Word or Microsoft Excel are only affected if you use 32-bit versions. Then users might get the error message "Document not saved" when saving. If the error occurs, one should repeat the last file operation, Microsoft writes in its recommendation for a workaround.

Microsoft writes that end users in the home or in small businesses that use Windows in unmanaged environments are probably not affected either. Currently, Microsoft is working on a solution for the problem, which affects the following Windows clients.

  • Windows 11 21H2 tills 22H2
  • Windows 10 21H2 till 22H2

Start menu, search, UWP apps

The second issue  was mentioned in the Windows Release Health Dashboard under Known Issue in the article Start menu, Windows Search and UWP apps might have issues opening as of May 18, 2023. The issues, which have been known since January 2023, are listed as "mitigated". Microsoft writes about this:


Start menu, Windows Search and Universal Windows Platform (UWP) apps might not work as expected or have issues opening.

Microsoft states that the cause is corrupted registry entries or data in Windows. This affects the Microsoft Office APIs for integration with Windows, Microsoft Office, or Microsoft Outlook or Outlook Calendar.

An example of an application affected by this problem is ClickShare, Microsoft writes. I had pointed out this very problem in my blog post Windows 10: Taskbar and Office apps suddenly broken (Jan. 18, 2023). Microsoft now states that the underlying problem is not caused by installing a Windows update. Rather, it could be caused by an update to an affected application. The following Windows clients are affected.

  • Windows 11 21H2 tills 22H2
  • Windows 10 21H2 till 22H2

Microsoft is still working on a solution to this problem and plans to provide it with one of the next updates. To mitigate the problem, Microsoft suggests uninstalling the applications that integrate with Windows, Microsoft Office, Microsoft Outlook or Outlook Calendar and cause problems. One straw of hope left with Microsoft is that the vendors of these applications will provide an update that fixes the problem. For you ClickShare from Barco there are the two articles:

Unresponsive Windows taskbar or user shell folder permissions issues with ClickShare App Calendar integration

Issues with speech recognition (Chinese, Japanese)

In Windows 11 22H2 users from China and Japan may have had the problem that speech recognition does not always work. With date of May 24, 2023 Microsoft writes in the article Intermittent issues with speech recognition when using Chinese or Japanese that these isses are fixed with the update KB5026446.
