Microsoft no longer supports Windows 11 21H2 or Windows Server 2012
With the release of this month's security updates for Windows, Microsoft has brought to an end support for not only Windows Server 2012, but also Windows 11 21H2.
What this means for users of these versions of the operating system is that there will be no more updates of any sort made available -- and this means both security updates and non-security updates. For anyone who wants or needs to stick with Windows 2012, things could get expensive, but there are free upgrades available to those currently running Windows 11 21H2.
