VMware vSphere 6.7 is the last version that will support vCenter for Windows deployment. From the next version, vCSA will be the only option to run vCenter Server.

If you want to install vCenter for Windows with version 6.7 it is still fully supported deployment, but keep in mind that with the next upgrade, you will have to migrate vCenter for Windows to the vCSA.

vCenter Server provides the following services:

• Web Client: The vSphere Web Client lets you connect to vCenter Server instances by using a web browser so that you can manage your vSphere infrastructure.
• Inventory Service: This stores vCenter server inventory data and server application data. It also allows you to search the inventory objects across linked vCenter server instances.
• Profile driven storage: This is a component in VMware vSphere that allows users to intelligently provision applications, mapping VMs to storage levels according to pre-defined service levels, storage availability, performance requirements, or cost.
• Auto Deploy: This feature allows you to deploy and provision hundreds of physical servers and automatically install the ESXi hypervisor. Optionally, you can specify host profiles to apply to the hosts and a vCenter Server location (folder or cluster) for each host.
• Syslog Collector: ESXi system logs can be redirected to a vCenter server over the network, rather than storing them on a local disk. Using Syslog Collector, you can centralize the log management of all your ESXi servers.
• Network Dump Collector: This is the vCenter Server support tool. ESXi can be configured to save the VMkernel memory to a network server, rather than saving it to a disk when the system encounters a critical failure. Such memory dumps over the network will be collected by the  vSphere ESXi Dump Collector.

Since version 6.5,  vCenter Server Appliance is a preferred deployment type, and vCenter Server for Windows is still fully supported in vSphere 6.7 as well. If you want to follow VMware best practices, you should switch to vCSA.
