Windows VPS or Linux VPS?

When you order a VPS, one of the first choices is the operating system. Most servers run Linux, but Windows VPS plans exist for good reasons. The right choice depends almost entirely on the software you need to run, and then on cost, memory and how you like to work.

This guide compares the two fairly, shows which jobs suit each, and gives you a quick way to decide. If you already know you need Windows, what is a Windows VPS for? covers sizing, licences and day-one security in detail.

A few words you will see

Term	What it means
Windows Server	The edition of Windows made for servers.
Linux distribution	A packaged version of Linux, such as Ubuntu or Debian.
RDP	Remote Desktop: how you use a Windows server's desktop from another device.
SSH	The secure way to log in to a Linux server and type commands.
Package manager	The Linux tool that installs and updates software, such as apt.
Licence	Permission to use software. Windows and much Windows software need one. Most Linux software does not.

The one question that usually decides it

Does the software you need only run on Windows?

• If yes, choose Windows. No amount of saving makes up for software that will not run.
• If no, or if it has a Linux version, Linux is usually cheaper, lighter and has far more server guides, including almost every guide on this site.

Check the software's own documentation or download page. Many tools that started on Windows now have Linux or Docker versions.

Side by side

	Linux VPS	Windows VPS
Software licence	The system and most server software are free	Windows needs a licence, sometimes included in the plan price. Check the order page
Memory at idle	A minimal server uses roughly 100 to 200 MB	Much more, because of the desktop and background services
Smallest practical plan	512 MB to 1 GB for light jobs	About 2 GB, and 4 GB is more comfortable
How you manage it	Commands over SSH	A familiar desktop over Remote Desktop
Installing software	Package manager, Docker or the project's instructions	Installers, as on a normal PC
Web hosting	The standard choice for most web software	Mainly for apps built on Microsoft technology
Guides and community help	Huge, for almost every server job	Good for Windows tasks, fewer for self-hosting
Updates	Fast, can be fully automatic	Windows Update, often slower, with more reboots

Which job suits which

Job	Usually better on	Why
WordPress and most websites	Linux	The software is built and documented for it
A personal VPN	Linux	WireGuard is light and simple on Linux. See setting up a WireGuard VPN
Docker and self-hosted apps	Linux	Most containers are Linux containers
Bots, scripts and automation	Linux	Python and Node.js run well on small Linux plans
Learning servers	Linux	The skills apply to most hosting and cloud platforms
Windows-only desktop software that must run all day	Windows	It will not run on Linux
Apps for IIS, ASP.NET on .NET Framework, or Microsoft SQL Server	Windows	They are built for it
A remote Windows desktop for occasional tasks	Windows	That is exactly what it offers
Game servers	Either, depending on the game	Many have Linux versions. Some only ship for Windows. See VPS for game servers

Newer .NET apps often run on Linux too. Check the app's documentation before assuming it needs Windows.

Cost and memory

Two things make Windows more expensive for the same job:

• Licensing. Windows itself needs a licence, and some Windows server software, such as Microsoft SQL Server or extra Remote Desktop users, needs its own. Check what the plan includes and read Microsoft's current terms.
• Memory. A job that fits comfortably on a 1 GB Linux plan may need 2 GB to 4 GB on Windows, because Windows uses so much more at idle.

Compare the live plan lists on this page for the sizes each would need. For most non-Windows jobs, Linux comes out well ahead. Swap on Linux and the page file on Windows both help when memory briefly runs short, but neither is extra RAM.

How you work with each

Windows feels familiar. You connect with Remote Desktop and see a full desktop. You install software with installers and manage it with windows and menus. That is easier for many people at first, though it uses more bandwidth and memory.

Linux is managed through text commands over SSH. It looks harder at first, but most tasks are a few commands that you can copy from a guide, repeat exactly and automate. After a short learning curve, many people find it faster. How to connect with SSH and useful Linux server tools are good starting points.

Security differences

Neither system is safe by default on the open internet. Both need updates, strong logins and a firewall. The main differences:

• Remote Desktop is a big target. Bots try Windows passwords constantly. Limit Remote Desktop to your own IP address or a VPN. See what is a Windows VPS for?.
• SSH keys make Linux logins very strong. With keys only and passwords off, guessing is not possible. See securing your VPS.
• Updates. Linux security updates can install automatically in the background. Windows updates often need a reboot, so plan a regular time for them.
• Fewer programs, fewer risks. A minimal Linux server runs very little. A Windows server runs many services by default. On either, remove what you do not use.

A quick way to decide

1. List the software you need to run.
2. If any of it only runs on Windows, choose Windows, sized for it.
3. If everything runs on Linux, choose Linux, unless you have a strong reason to prefer a desktop.
4. If you are not sure, start with a small Linux plan to learn on. It costs little, and the skills last.

Choosing a Linux distribution is the next step. Why most servers run Linux, and which distribution to pick covers it.

Limits

• Licence terms are Microsoft's. Follow their current terms for Windows and Windows server software, not this summary.
• Both are unmanaged on RackNerd. You install, update and secure the system yourself.
• Fair use applies to both. Unmetered does not mean unlimited, and RackNerd's acceptable use policy covers what you run.
• No graphics card. Neither suits gaming, video editing or heavy graphics.

When to step up

On Windows, step up when the desktop is slow after updates finish or apps run out of memory: 4 GB is comfortable for light use, and 6 GB to 8 GB suits heavier apps. On Linux, the same jobs usually need less, so step up when memory runs short after adding apps.
