What is a “Windows Key Checker”

Microsoft Windows, as one of the most widely used operating systems globally, often comes pre-installed on new laptops or desktops.

While most users trust that the Windows they’re using is genuine, it’s vital to verify this, especially if you’ve purchased a second-hand device or if you’ve acquired the software from a source other than Microsoft.

This article guides you on how to check if your Windows key is genuine, using various methods including CMD, key finder tools, Microsoft’s own resources, and more for Windows 7, 10, and 11.

Windows Key Checker

What is a Windows Product Key?

A Windows product key is a 25-character code used to activate Windows. It looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. This key helps ensure that your copy of Windows is used according to the Software License Terms.

Checking Windows Key via CMD

The Command Prompt (CMD) is one of the quickest ways to check the authenticity of your Windows key. Here’s how you can use it:

  1. Press Win + R to open the Run dialog box.
  2. Type cmd and hit Enter to open the Command Prompt.
  3. In the Command Prompt, type slmgr.vbs -dli and hit Enter.

A window will pop up displaying information about your Windows license. The description will tell you if your Windows is genuine.

Checking Windows Key via System Properties

For Windows 10 and 11, you can check the authenticity of your Windows key via the System Properties:

  1. Press Win + X and choose ‘System’.
  2. Look for the ‘Windows activation’ section at the bottom.

If your copy of Windows is genuine, it should say “Windows is activated”.

Checking Windows Key for Windows 7

For Windows 7, you can check your Windows key’s authenticity through the Control Panel:

  1. Click ‘Start’, right-click ‘Computer’ and click ‘Properties’.
  2. Scroll down to ‘Windows activation’.

If your Windows 7 is genuine, it should say “Windows is activated”.

Checking Windows Key on a Laptop

If your Windows came pre-installed on your laptop, you could verify its authenticity using the same methods mentioned above (CMD, System Properties, Control Panel).

Checking Windows Key via Microsoft’s Software

You can also use Microsoft’s software to check if your Windows is genuine. Visit the Microsoft Genuine Advantage Diagnostic Tool page and click on ‘Run Diagnostic Test’. This tool will check your Windows and Office to ensure they’re genuine.

Using Key Finder Tools

There are several third-party tools like ‘ProduKey’ and ‘ShowKeyPlus’ that can help you find your Windows key. These tools can be helpful if you’ve lost the original key and need to verify it. However, do note that these tools don’t confirm the authenticity of the key; they only display it.

Using a Key Tester

A key tester, like the Microsoft PID Checker, can verify if your product key is valid. Simply download the tool, enter your product key, and the program will confirm if it’s a valid key.

Windows Key Shortcuts

While not directly related to checking key authenticity, knowing some handy Windows key shortcuts can improve your productivity:

  1. Win + E: Opens File Explorer
  2. Win + I: Opens Settings
  3. Win + D: Show/hide desktop
  4. Win + L: Lock your PC or switch accounts

In conclusion, checking the genuineness of your Windows key is crucial to ensure you’re using an authentic, secure product. By following the methods outlined above, you can confirm your product key’s authenticity and enjoy peace of mind.
