We also noticed that Microsoft quietly updated its documentation on June 2, announcing that it will provide this feature update more widely. The company said it is now using its machine learning and artificial intelligence methods to automatically upgrade devices running the 2004 version to the 21H1 version.
If you still cannot see the update for some reason, you can wait a few days/weeks. You can also force the installation through the Windows 10 media creation tool or "Windows Yisheng".
If you want a fresh installation, you can also use the media creation tool to download the Windows 10 ISO file and create a bootable USB disk."We will continue to train our machine learning through all stages to intelligently launch a new version of Windows 10 and provide a smooth update experience," Microsoft pointed out.
Although the latest May 2021 update has some known issues, fortunately, these bugs have not been widely reported. If you do encounter minor problems after the upgrade, there are solutions.
For example, a bug in Windows 10 May 2021 update or earlier may cause unexpected audio problems. According to a new proposal, users can hear some noise when using certain settings of 5.1 audio.
This issue only affects certain applications, audio devices, and settings combinations. If you encounter audio problems, Microsoft recommends switching to spatial sound settings, such as Dolby and Windows Sonic.
The second known issue is that part of the automatic Japanese phonetic kana input/conversion function does not work in some applications.
