What Is Windows Server and How Is It Different From Windows

Whatis Windows Server, and what is it used for? Here's how Windows Server differs from consumer editions of the OS. If you're a regular computer user, you may have only come across the consumer-facing editions of Windows. But did you know that Microsoft also publishes an entire Windows Server line of its operating system? Let's look at the differences between Windows Server and regular Windows. We'll see what Windows Server includes, what it leaves out, and why it's so different.

What Is Windows Server?

Essentially, Windows Server is a line of operating systems that Microsoft specifically creates for use on a server. Servers are extremely powerful machines designed to run constantly and provide resources for other computers. This means that Windows Server is only used in business settings in almost all cases.

Microsoft has published Windows Server under this name since Windows Server 2003 launched in April 2003. However, even before this, server versions of Windows were available. For instance, Windows NT 4.0 was available in both workstations (for general use) and server flavors. Normal users don't need to worry about Windows Server in almost all cases. You won't find it on the shelf in stores or accidentally download it from Microsoft when you mean to get the standard version of Windows. But it's still interesting to learn about, so you're aware.

Windows Server vs. Regular Windows: The Basics

With just a glance, you might have trouble telling the difference between Windows Server and normal versions of Windows. The desktop looks the same, including the taskbar, desktop icons, and Start button. As it turns out, every Windows Server release corresponds to a consumer version of Windows. Windows Server 2003, for instance, is the server version of Windows XP. Current versions include Windows Server 2016, based on the Windows 10 Anniversary Update, and Windows Server 2019, based on version 1809 of Windows 10.

THE LATEST WINDOWS 10 VERSION WON'T BE THE LAST ONE

Because Windows Server and Windows share a codebase, you can perform many of the same functions on both. You can download and install programs like browsers and photo editors on Windows Server, and many Windows basics like Notepad are included in Windows Server.

However, Windows Server and Windows Pro/Home have more differences than similarities. Let's review some of them.

Windows Server Includes Enterprise Management Software

Because Windows Server is intended for businesses, it includes plenty of enterprise software. Below are a few roles that a server can perform thanks to these tools:

Active Directory: Active Directory is a user management service that allows a server to act as a domain controller. Instead of each user logging into a local computer, the domain controller handles all user account authentication. See our explanation of Windows domains for more on this.

DHCP: Dynamic Host Configuration Protocol is a protocol that lets a server automatically assign IP addresses to all devices on the network. At home, your router probably handles this. But in a business setting, IT staff can take advantage of the greater DHCP functionality in Windows Server.

File and Storage: Having a file server for your company is another common use. This lets you keep important data in a central location and set permissions to control who can access which files.

Print Services: If a business has dozens of printers across the building, it's a waste of time for IT staff to configure them individually for each new workstation. Setting up a print server lets you easily map printers to computers and reduce redundant work.

Windows Update Services: Often, businesses don't want all Windows updates to come through right away. By setting up a server as a Windows Update controller, you can route all workstation updates through that server and configure specific rules for how they should work.

These are only a few of the server roles Windows Server can handle. Often, a company will have more than one server and split the above roles across multiple devices. Standard copies of Windows don't include these capabilities out of the box. You can install third-party tools to replicate some of this functionality, but it won't be as robust.

Windows Server Has FewerHardware Limitations

Most people don't worry about the maximum amount of RAM they can put in their computer. A 64-bit installation of Windows 10 Pro allows you to install up to a huge 2TB of RAM. However, most users don't have more than 32GB of RAM in their systems, so even installing 1TB of RAM is far out of the question.

Knowing this, can you believe that Windows Server supports up to 24TB of RAM? It also allows you to use up to 64 CPU sockets, much greater than the two sockets that Windows 10 Pro supports. There are good reasons for these high hardware caps. A server can power important functionality for hundreds of people in a business, so it often needs to be extremely powerful. For instance, a server running dozens of virtual machines needs loads of RAM to keep them all running smoothly at the same time. This points out another important factor of Windows Server: it doesn't always run on physical hardware. Some businesses purchase a few physical servers and then run many virtual machines (with Windows Server) to handle different functions, like those discussed above.

 

Windows Server Doesn't Include Extraneous Features.

As you'd expect, Windows Server retains power-user features like the Command Prompt and other administrative tools. However, Server editions of Windows strip out a lot of the quality-of-life features that Windows 10 includes. For example, in Windows Server 2016 and 2019, you won't see the Microsoft Store, Cortana, and other new Windows 10 features. It doesn't bundle in apps like Your Phone, and even on Windows Server 2019, you have to download Microsoft Edge separately. Windows Server OSes also don't let you log in with a Microsoft account. Because they're designed for enterprise use, you don't need these consumer-facing tools on a server OS.

Additionally, some apps check to see if you're using Windows Server before installing them. In some cases, the app won't work on a server version of Windows. Windows Server is also much more locked down by default. It still uses Internet Explorer as the default browser, but the security settings are much more restrictive than usual. This makes sense, as having a server compromised would be catastrophic compared to just one workstation.

Windows Server's Pricing Differs

As you may expect from a business-oriented product, Windows Server doesn't come cheap. It's much more expensive than a consumer version of Windows and comes in various flavors depending on your needs. Microsoft's Windows Server 2019 pricing page gives an idea of what you might pay for the server OS. Depending on how many people will access the server, you also need to pay for CALs (Client Access Licenses) to use the services legally.

As mentioned above, businesses historically installed Windows Server on a physical onsite server, which has much greater hardware capabilities than a workstation. However, you also can run Windows Server in a cloud service like Microsoft Azure. This allows you to offload the burden of maintaining a physical server to a cloud provider like Microsoft. In addition, this enables companies to spread the cost of upgrading out over a subscription instead of paying all at once for a new physical server. What works best depends on the specific organization's needs.

Now You Understand Windows Server

Though Windows Server and regular Windows share common code and look similar, they're for totally different uses. Consumer editions of Windows 10 are designed for maximum usability and don't include software intended for enterprise use. Meanwhile, Windows Server isn't concerned with looking pretty. Its purpose is to run many services reliably that enterprise users need. These are far from the only Windows versions, either. For example, Microsoft offers Windows 10 Enterprise, which includes more functionality than Windows 10 Pro.
