Minimum System Requirements for Windows 10 version 21H1

Windows 10 21H1 will no longer come as a major feature update of the year 2021. Rather, this will be a minor update to already in-use Windows operating systems i.e. version 2004 or 2009. Microsoft has already announced that this will come in the form of a cumulative update and replaces the existing ones. In this post, we will discuss the minimum processor, hardware, and system requirements to download and install Windows 10 21H1 to your device.

As this is merely an extension to Windows 10 version 20H1 or 20H2, there are no changes in the required hardware and processor. Usually, there is speculation of an increase in storage while upgrading to a new version of Windows 10. Rest assured, as the storage requirements for Windows 10 21H1 remain the same as that of version 1903/1909/2004/2009 i.e. a minimum of 32 GB.
