- Microsoft has officially released Windows 10 21H1 (May 2021 Update) on May 18, 2021.
- The new version is available for versions 20H2 and 2004 with an enablement package.
- Older versions of Windows 10 can upgrade to version 21H1 but as a full reinstallation.
The Windows 10 May 2021 Update (version 21H1) is rolling out as a free update for compatible devices starting on May 18, 2021. This is the eleventh feature update available for desktops, laptops, and tablets that introduces a small set of improvements and features to enhance productivity and security.
The new version is available as an optional install through the Windows Update settings. Since this is an update based on the same core system files available on version 20H2 and 2004, devices running the last two versions will receive the new feature update as a small enablement package that will install as a cumulative update without the need for reinstallation. However, if your device is running a version nearing the end of service (such as version 1909), then Windows 10 will eventually download and install the new version automatically.
Download Windows 10 21H1, May 2021 Update
Starting on May 18, 2021, if the computer has version 20H2 or 2004, you can upgrade manually to the May 2021 Update (version 21H1) by checking the “Windows Update” settings page and clicking the Download and install option. After the package downloads, the computer will need to restart to complete applying the new version. The entire upgrade process should only take around five minutes. If the installation option is missing, the new version still not fully compatible with your hardware and software configuration.
If you have an older version, you can still install version 21H1 through Windows Update. However, it may take a while before the update becomes available for your device since Microsoft is initially only updating versions 20H2 and 2004. Also, remember that upgrading from version 1909 or older will require full reinstallation.
Update Assistant and Media Creation Tool
Alternatively, you can download Windows 10 21H1 manually using the Update Assistant, which allows you to force the upgrade in case that Windows Update is not working. Also, you can use the Media Creation Tool to perform an in-place upgrade without losing your files, but consider using these tools will require a complete reinstallation of the operating system.
You can even use the Media Creation Tool to perform a clean install of the May 2021 Update, which can help fix problems and improve performance. Also, you can download the ISO file with version 21H1 to perform an in-place upgrade or clean install from USB.
