OS requirements
The following table shows which 64-bit non-Core Microsoft Windows Server OSes are supported for the each of the different software packages that comprise a Horizon infrastructure. App Volumes host OS requirements will be outlined separately in Chapter 11, Implementing App Volumes:
While VMware vCenter and the different Horizon servers support a number of different Windows OSes, use of the newest supported version is recommended to ensure that the servers will not be impacted by any changes in OS support by Microsoft. Additionally, you never know when vSphere or Horizon itself will end support for older OSes, which would impact your ability to perform in-place upgrades.
As Horizon Composer supports only Windows Server 2008 R2 SP1, 2012 R2, and 2016, any Horizon installation that plans on deploying linked-clone desktops and installing Composer directly on the vCenter Server will need to choose that specific version of Windows. Refer to the VMware document Horizon 7 Installation (https://docs.vmware.com/en/VMware-Horizon-7/index.html) for updated information regarding which Windows OSes are supported.
