On May 18, Microsoft confirmed officially that users can download the Windows 10 21H1 update if they use any of the existing tools:
- Via Windows Update, but it will probably be delayed because the update is released gradually.
- Update Assistant (to upgrade the existing installation)
- Media Creation Tool (for upgrading the existing installation or for a new installation with version 21H1)
- Installation image (.ISO).
The May 2021 Update is not a big release and there is nothing essential for the end user.
Such as we mention for a long time changelog, the functions of Windows 10 version 21H1 are aimed at corporate customers and those who use Windows Hello with multiple cameras.
In other words, there is no reason to install this feature update today. The only change you will notice is the new OS version and version numbers.
