How to upgrade Windows 10 version 21H1 to 21H2 right now (KB5003791)

Microsoft plans to release Windows 10 version 21H2 this year. Windows 10 devices that run versions 2004, 20H2 or 21H1 can be upgraded to the new version of Windows 10 almost effortlessly, as the update will install just like any normal update for the operating system.

Windows 10 will be supported until 2025 with updates. Microsoft has not revealed much about its plans for the operating system besides that, but all things point to a scenario in which Windows 11 is the main focus and Windows 10 will receive smaller updates that fix bugs and correct security issues for the most part.

Windows 10 version 21H2 adds a small number of features, most of them for business and Enterprise customers.

The update to Windows 10 version 21H2 is delivered via an enablement package. It has been pushed to the release preview channel already and can also be installed on non-Insider devices running recent versions of Windows 10.

The update KB5003791 can be downloaded from Microsoft’s Windows Update server. It needs to be installed manually on eligible devices.

Note: Most Windows users may want to wait with the installation of Windows 10 version 21H2 as there is little gained by installing it right away. In any event, it is advised to create a backup of the system before proceeding, even though there is only a slim chance that things may go wrong in the process.

Closing Words

Windows 10 version 21H2 is a small update, just like 21H1 and 20H2. There is little incentive to install these updates at all at this point. It seems unlikely that Microsoft will produce a larger feature update for Windows 10 in the coming years, more likely that users will get these smaller feature updates that introduce little to no new features on Windows 10.

Now You: will you stay on Windows 10 or upgrade to Windows 11? (via Deskmodder)
