On May 18, Microsoft unleashed the Windows 10 21H1 (May 2021 Update) to millions of compatible devices around the world, and along with the kick-off of the rollout, the software giant also published a list of known issues with the new version.

The list of known issues was published at the Windows 10 health dashboard website, and at the time of this writing, it only lists two problems that have been already mitigated. On affected computers, the company is placing a compatibility hold to block the update to safeguard the experience.

Known issues for Windows 10 21H1

Here’s a list of the known issues for Windows 10 21H1:

  • News and interests button on the Windows taskbar might have blurry text.
  • Apps might have issues accessing event logs on remote devices. (Resolved on June 6, 2021.)
  • A high-pitched noise might be heard when using 5.1 audio with certain settings. (Mitigated on May 18, 2021.)
  • Automatic input of Furigana might not work as expected. (Mitigated on May 18, 2021.)

While it is good to see that a rollout is off to a good start, this is expected since it is a small update that does not include significant changes, and Microsoft has been proactively fixing many issues during the past several months.

Also, the software giant is using a gradual rollout approach, and it’s only making the 21H1 update available for devices known to have a smooth upgrade experience.

Although the new feature update does not have big problems, as more devices install version 21H1, Microsoft will probably continue to update the dashboard page with more problems and workarounds as necessary.

Update June 15, 2021: This article has been updated to reflect the new problems confirmed by Microsoft for version 21H1.
