Windows Server 2019 with April 2021 updates.

Windows 10 is a series of personal computer operating systems produced by Microsoft as part of its Windows NT family of operating systems. It is the successor to Windows 8.1, and was released to manufacturing on July 15, 2015, and to retail on July 29, 2015. Windows 10 receives new releases on an ongoing basis, which are available at no additional cost to users. Devices in enterprise environments can receive these updates at a slower pace, or use long-term support milestones that only receive critical updates, such as security patches, over their ten-year lifespan of extended support.

The assembly is based on the original MSDN images. Updates up to April 13, 2021 were integrated, and SmartFix 2.3.11 and Microsoft DaRT were integrated. There are no cosmetic changes in it and nothing is cut!
