What is Windows Server, and which edition should you run?

If you’ve ordered a Windows VPS, the first decision you’ll usually need to make is which version and edition of Windows Server to run. This post covers what Windows Server actually is, which versions are currently supported, and how to choose between Standard and Datacenter, and between the full desktop experience and Server Core.

What Windows Server is

Windows Server is Microsoft’s server operating system, built on the same core as desktop Windows but stripped of consumer features and extended with server roles: IIS for web hosting, Active Directory for identity management, DNS and DHCP, Hyper-V for virtualisation, and so on. Unlike desktop Windows, it’s licensed and supported for long-running, unattended workloads and comes with a much longer support lifecycle.

Which versions are currently supported

Microsoft releases a new Long-Term Servicing Channel (LTSC) version of Windows Server roughly every two to three years, each with five years of mainstream support followed by five years of extended support (security updates only, no new features). As of today, three versions are in active support:

• Windows Server 2019: in extended support, running until 10 January 2029.
• Windows Server 2022: mainstream support ends 14 October 2026, with extended support continuing until 15 October 2031.
• Windows Server 2025: the current release, generally available since November 2024. Mainstream support runs until 14 November 2029, extended support until 15 November 2034.

For a new deployment, Windows Server 2025 or Windows Server 2022 are the sensible choices. Windows Server 2019 still works and is still supported, but with mainstream support already closed and a shorter runway left, there’s little reason to pick it for something new. Always check the current dates on Microsoft’s official lifecycle pages before committing, since these policies can change.

Standard vs Datacenter edition

Both editions include the same core Windows Server features and roles. The difference that actually matters for most people is virtualisation rights:

• Standard: licensed for up to two virtual machines (or one physical instance plus one virtual, at that licence tier) per fully licensed physical host. You can “stack” additional Standard licences on the same host to run more VMs.
• Datacenter: unlimited virtual machines on a fully licensed host, plus some extra features aimed at large-scale virtualised and software-defined datacentre environments (such as Storage Spaces Direct and Shielded VMs).

If you’re running a single VPS as a single instance of Windows Server, the difference is largely academic: you’re consuming one instance either way, and your hosting provider handles the underlying host licensing. Datacenter only becomes relevant if you’re licensing your own bare-metal hardware and plan to run many Windows Server VMs on it.

Desktop Experience vs Server Core

At install time, Windows Server offers two options:

• Desktop Experience: the full graphical interface, including Server Manager, File Explorer, and the Start menu. This is what most people picture when they think of Windows.
• Server Core: a minimal installation with no GUI shell. You manage it via PowerShell, the command line, or remote tools such as Server Manager or Windows Admin Center running on another machine.

Server Core has a smaller attack surface, fewer components to patch, and uses less disk and memory. It’s the better choice if you’re comfortable managing Windows entirely through PowerShell and remote administration tools.

Our honest recommendation

For a typical unmanaged VPS, we’d suggest:

• Windows Server 2022 or 2025, Standard edition, unless you specifically know you need Datacenter’s unlimited VM rights.
• Desktop Experience (GUI), unless you’re already comfortable administering Windows purely through PowerShell and RDP-free remote tools. Server Core is genuinely more secure and efficient, but it has a learning curve, and troubleshooting an unfamiliar system without a GUI at 2am is not where you want to be building that skill.

You can always move to Server Core later once you’re confident managing the box remotely, though note that current versions of Windows Server don’t support converting between Server Core and Desktop Experience after installation, so switching means a clean reinstall with the other option selected. Start with what you can actually operate, or if you’d rather not manage patching and updates on any of this yourself, Managed Cloud Hosting takes that off your hands.
