One of the changes with vSphere 6.5 Update 1 is how VMware Tools are bundled. This will primarily affect those who have older Windows systems, or are running operating systems outside of Windows or Linux.
Each build of ESXi contains ISO images for the current VMware tools installer for guest operating systems that run on top of it.
