A Quick Guide to Install Windows Server Core

When you set out to install Windows Server, one of the most important decisions you'll make is whether to go with Server Core or Server with Desktop Experience. If you want a lightweight, secure, and resource-efficient server, Server Core is the way to go.

Here's a step-by-step guide to get you up and running with a Server Core installation.

Step 1: Connect to the Installation Source

First, make sure your server can boot from the installation media, whether it's a USB drive, a DVD, or an ISO file mounted to a virtual machine. When the installer launches, you'll be greeted by the initial setup screen.

Step 2: Choose Language, Time, and Keyboard

Select your preferred language, time and currency format, and keyboard layout. Once you've made your choices, click "Next" to continue.

Step 3: Select the OS to Install

This is the most critical step. You'll see a list of available Windows Server editions. To install Server Core, select the edition that does NOT have "(Desktop Experience)" in its name. For example, choose "Windows Server 2022 Standard" instead of "Windows Server 2022 Standard (Desktop Experience)".

Step 4: Accept License Terms

Read through the license terms and check the box to accept them. Click "Next" to proceed.

Step 5: Choose Installation Type

You'll be asked what type of installation you want. Since you're performing a new installation, select "Custom: Install Windows only (advanced)". This option lets you choose where to install the OS.

Step 6: Choose Install Disk

Select the disk or partition where you want to install Windows Server. If you need to create or format a partition, you can do so here. Click "Next" to start the installation. The process will begin copying files and installing the OS.

Step 7: Provide Administrator Password

After the installation is complete and the server restarts, you'll be prompted to provide an administrator password. This is required before you can log in for the first time. Enter a strong password, confirm it, and press "Enter".

Congratulations! You've successfully installed Windows Server Core.

Why Choose Server Core?

Server Core is a command-line-only interface. There's no Start Menu, desktop, or graphical shell. While this may seem intimidating, it's perfect for roles like a web server, DNS, or Active Directory because it offers several key advantages:

• Smaller Footprint: It uses less disk space and requires less memory.

• Reduced Attack Surface: With fewer running services and components, there are fewer potential entry points for attackers.

• Fewer Updates: It often requires fewer patches and restarts, leading to better uptime.

When Should You AVOID Server Core?

Despite its benefits, Server Core isn't the right choice for every situation. You should avoid Server Core if:

• You're Not Comfortable with the Command Line: All management is done via the command line (PowerShell or SConfig). If you're not familiar with these tools, managing the server will be difficult and time-consuming.

• You Need a GUI for Specific Applications: Some server roles and applications—such as Remote Desktop Services (RDS), Microsoft Exchange Server, or any third-party software that requires a graphical interface for installation or management—simply won't work on Server Core.

• You Prefer Local Management with Visual Tools: If you like to manage your server directly from a GUI using familiar tools like Device Manager, Event Viewer, or other snap-ins, you'll be much more productive with the Desktop Experience.

In short, while Server Core is a more secure and efficient choice, the Desktop Experience is a better fit if your needs or applications require a full graphical interface.
