Learn What Version of Windows You Have

Understanding Windows Versions and Why It Matters

Windows is an operating system made by Microsoft that runs on computers, laptops, and tablets. Since its first release in 1985, Microsoft has created many different versions of Windows. Each version has its own features, security updates, and support timeline. Knowing which version you have is important because it affects which programs you can run, how secure your computer is, and when Microsoft will stop providing updates.

As of 2024, the most commonly used Windows versions are Windows 10 and Windows 11. Windows 10 was released in 2015 and remains popular on millions of computers worldwide. Windows 11, released in 2021, introduced a redesigned interface and new security features. However, older versions like Windows 7 and Windows 8.1 are still found on some computers, though they no longer receive security updates from Microsoft.

Your Windows version determines what features are available to you. For example, Windows 11 includes features like widgets, Snap layouts, and improved virtual desktop management that don't exist in Windows 10. Some software programs require a specific version of Windows to run properly. If your computer is running an outdated version, you may not be able to use newer applications or receive important security patches that protect against viruses and hacking attempts.

Microsoft stops supporting older versions after a certain date. When support ends, the company no longer releases security updates for that version. This means computers running unsupported versions become increasingly vulnerable to security threats. Understanding your Windows version helps you know whether your computer is still receiving protection from Microsoft.

Practical takeaway: Identify your Windows version first, then you can make informed decisions about software compatibility, security updates, and whether upgrading might benefit your needs.

How to Check Your Windows Version Using Settings

The most straightforward way to find your Windows version is through the Settings app. This method works on Windows 10 and Windows 11 and takes about two minutes. Open Settings by clicking the Start button (the Windows logo in the bottom left corner), then type "Settings" and press Enter. Alternatively, you can press the keyboard combination Windows key + I to open Settings directly.

Once Settings opens, look for a section called "System" on the left side of the window. Click on "System" to expand the menu. Then scroll down and look for an option labeled "About." Click on "About" and Windows will display detailed information about your system. In the "About" section, you'll see several pieces of information. Look for the line that says "Edition" — this shows your Windows version, such as "Windows 10 Home" or "Windows 11 Pro."

Below the Edition line, you may also see other useful information. The "Version" number shows which update of Windows you have. For example, you might see "Version 23H2" for Windows 11 or "Version 22H2" for Windows 10. The "OS Build" number is even more specific and shows the exact build number of your system. You'll also see information about your system's processor, RAM (memory), and system type (32-bit or 64-bit).

Write down or take a screenshot of this information, as it can be useful if you need to troubleshoot problems, purchase software, or contact technical support. The information in the About section is static — it won't change unless you update Windows or upgrade to a different version. This makes it a reliable reference point.

Practical takeaway: Use Settings > System > About as your primary method for checking your Windows version, version number, and OS build — all in one convenient location.

Using System Information for Detailed Windows Details

The System Information utility provides more technical details about your Windows installation than the Settings app. This tool is particularly useful if you need comprehensive information for troubleshooting or checking hardware specifications. To open System Information, click the Start button, type "System Information" and press Enter. Alternatively, you can right-click "This PC" or "My Computer" on your desktop, select Properties, and look for a link to System Information.

The System Information window displays data in a structured format. At the top, you'll see basic system details including your computer's name, manufacturer, and model. Most importantly, look for the line labeled "OS Name" — this clearly states your Windows version. You might see entries like "Microsoft Windows 10 Home" or "Microsoft Windows 11 Professional." Just below that, you'll find "System Type," which indicates whether your Windows is 32-bit or 64-bit. Most modern computers run 64-bit Windows, which can address more memory and generally perform better.

The System Information window also shows your "OS Build" number, which identifies the exact version of your Windows installation. This build number changes with each major update Microsoft releases. For instance, Windows 10 has had dozens of builds since its release, with build numbers in the 19000+ range by 2024. Windows 11 builds are in the 22000+ range. The System Information tool also displays your processor type, installed RAM, and whether Hyper-V virtualization is supported — useful details for someone planning to run virtual machines or containers.

This tool was particularly important in the past when diagnosing computer problems. Many technical support professionals would ask for this exact information to troubleshoot issues. Today, while less critical for everyday use, System Information remains a valuable resource for advanced users, IT professionals, and anyone needing to verify specific hardware and software specifications.

Practical takeaway: Use System Information when you need detailed technical specifications beyond basic version information, especially for hardware details and exact OS build numbers.

Checking Windows Version on Older Operating Systems

If your computer is running Windows 7, Windows Vista, or Windows XP, the methods for checking your version differ slightly from Windows 10 and 11. These older systems no longer receive updates from Microsoft, but the methods to identify them remain consistent with how they were originally designed. Understanding how to find version information on older systems helps if you're working with legacy computers or managing equipment that hasn't been upgraded.

On Windows 7 and Windows Vista, you can find version information by clicking the Start button and typing "System" directly into the search box. Select "View basic information about your computer," which opens a window displaying your OS version. The window will clearly show "Windows 7" or "Windows Vista" along with the service pack number. A service pack is a collection of updates released together. For example, Windows 7 had Service Pack 1, and older versions had multiple service packs. On Windows XP, the process is similar — open the Start menu, right-click "My Computer," and select "Properties" to see the version and service pack information.

It's important to note that Microsoft stopped supporting Windows 7 in January 2020, Windows Vista in April 2017, and Windows XP in April 2014. This means these systems no longer receive security updates. If you encounter a computer running one of these versions, be aware that it poses security risks because it won't be protected against newly discovered threats. Modern software and websites increasingly require Windows 10 or 11 to function properly, so older systems may not run current applications.

If you find that you're working with a computer running Windows 7 or older, consider discussing an upgrade path with relevant stakeholders. While upgrading costs money and requires planning, continuing to use unsupported operating systems exposes computers to significant security vulnerabilities. Many organizations have established timelines for transitioning away from older systems to maintain security and operational efficiency.

Practical takeaway: While older Windows versions can still be identified using built-in tools, recognize that versions prior to Windows 10 no longer receive security updates and may not support modern software.

Distinguishing Between Windows Editions and Versions

Windows comes in different editions, and the edition you have affects available features and pricing. The main editions are Home, Professional (Pro), Enterprise, and Education. Understanding the difference between your edition and your version prevents confusion when researching software compatibility or system requirements. Edition refers to which "flavor" of Windows you purchased, while version refers to the specific release number (Windows 10, Windows 11, etc.).

Windows 10 and 11 Home editions are designed for personal computers and include all essential features most people need for everyday tasks like web browsing, email, document editing, and media consumption. Home editions support features like Windows Update, Windows Defender antivirus, and built-in backup tools. The Home edition cannot join a corporate domain, which limits its usefulness
