The fastest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "settings", then select the Settings icon. Go to System in the left sidebar, then scroll down and click About. Your Windows version appears under "Edition" — it will say something like "Windows 10 Home" or "Windows 10 Pro". The build number (a longer string of digits) appears just below it under "OS Build".

This method takes about 10 seconds and shows you both the edition type and the exact build your computer is running. The build number matters if you're troubleshooting a specific problem or checking whether you have the latest updates.

Key Takeaways

  • The Settings app's About section shows your Windows edition and build number in one place.
  • The Windows key + Pause/Break keyboard shortcut opens the System window directly, skipping the Settings app entirely.
  • The build number tells you how current your installation is; higher numbers mean more recent updates.
  • You can also right-click "This PC" on your desktop or in File Explorer and select Properties to reach the same information.

Using the keyboard shortcut for instant access

Press the Windows key + Pause/Break together. This opens the System window directly without going through Settings. Your Windows edition and build number appear in the middle of the window under "System".

This is the quickest method if you know the keyboard shortcut. The Pause/Break key is usually in the upper right area of your keyboard, sometimes labeled just "Pause". On some laptops without a dedicated Pause key, you may need to hold Function (Fn) and press the key that has Pause printed on it.

Checking through File Explorer and This PC

Right-click the This PC icon on your desktop or in File Explorer's left sidebar. Select Properties from the menu. A window opens showing your system information, including Windows edition and build number in the middle section.

This route works the same way as the keyboard shortcut but takes a few extra clicks. It's useful if you're already in File Explorer looking at your files and want to check your version without switching to Settings.

Understanding what the version numbers mean

Windows 10 comes in several editions: Home, Pro, Enterprise, and Education. The edition determines which features you have access to. Home is the standard consumer version. Pro adds features like Remote Desktop and BitLocker encryption. Enterprise and Education are for organizations and schools.

The build number is a longer string like "19045.3693" that tells you exactly which update your computer has installed. Microsoft releases updates regularly, and each one gets a new build number. A higher build number means your computer has more recent security patches and bug fixes. You can compare your build number to Microsoft's official list to see how current your installation is.

What to do if you see "Windows 10 S Mode"

If your About page shows "Windows 10 S Mode" or mentions S Mode, your computer is running a restricted version of Windows 10 that only allows apps from the Microsoft Store. You can switch out of S Mode through Settings if you want to install programs from other sources, though the process is permanent and cannot be reversed.

S Mode is designed for security and simplicity on new computers, particularly in schools and for younger users. If you need to run software that isn't available in the Microsoft Store, you'll need to exit S Mode first. The option to switch appears in the Settings app under System > About, usually near the bottom of the page.

Checking your version from the command line

If you prefer using text commands, you can open Command Prompt or PowerShell and type systeminfo, then press Enter. The window displays a list of system details, including "OS Name" (your edition) and "OS Version" (your build number). This method shows the same information as the Settings app but in a different format.

Command Prompt is useful if you're already working in a terminal window or if you want to save the information to a text file for later reference. Right-click in the Command Prompt window and select "Select All", then press Ctrl+C to copy the text, and paste it into Notepad or any text editor.

Why you might need to know your version

Knowing your Windows version matters for several reasons. Software developers sometimes list Windows 10 edition requirements — certain programs may need Pro instead of Home. Your build number tells you whether you're up to date with security patches, which is important for protecting your computer from threats. If you're troubleshooting a problem online, support forums often ask for your build number to narrow down whether the issue affects all versions or just specific builds.

You also need this information if you're upgrading to Windows 11, since not all editions of Windows 10 upgrade to the same edition of Windows 11. Checking your current version before an upgrade prevents surprises about which features will be available afterward.

Frequently Asked Questions

What's the difference between Windows 10 Home and Pro?

Pro includes features Home doesn't have: Remote Desktop (controlling your computer from another device), BitLocker encryption, Hyper-V virtualization, and Group Policy management. Most home users don't need these features. Pro is designed for small businesses and power users who need advanced security or system management tools.

Does my build number need to match everyone else's?

No. Build numbers vary based on when your computer last checked for updates. Two computers updated on different days will have different build numbers. As long as your build number is recent (within the last few months), you have the current security patches. Microsoft releases updates regularly, so your number will change over time.

Can I upgrade from Windows 10 Home to Pro?

Yes. Open Settings, go to System > About, and scroll to the bottom. You'll see an option to upgrade to Pro if your computer meets the requirements. You'll need to purchase a license key, which Microsoft sells through the Settings app or through retailers. The upgrade keeps your files and programs intact.

What if my build number is very old?

Your computer may have updates waiting to install. Open Settings, go to Update & Security, and click "Check for updates". Windows will download and install any pending updates, which will increase your build number. Restart your computer if prompted. Keeping your build number current protects you from security vulnerabilities.

Is there a way to see version history on my computer?

Windows doesn't keep a built-in log of past build numbers you've had. However, you can check the Windows Update history in Settings under Update & Security > Update History to see which updates have been installed and when. This shows you the progression of updates but not the exact build numbers from past dates.
