To check if your Windows is original, you can use several methods

Here are some steps you can follow:

1. Check Activation Status

Windows 10:

1. Settings Method:

   • Open Settings (Press Windows + I).
   • Go to Update & Security.
   • Select Activation.
   • Here, you will see if your Windows is activated. If it says "Windows is activated with a digital license" or "Windows is activated with a digital license linked to your Microsoft account," your copy of Windows is genuine.

2. Control Panel Method:

   • Open Control Panel.
   • Go to System and Security.
   • Click on System.
   • Scroll down to the Windows activation section. Here, you will see the activation status.

3. Command Prompt Method:

   • Press Windows + R, type cmd, and press Enter to open Command Prompt.
   • Type slmgr /xpr and press Enter.
   • A window will pop up indicating the activation status of your Windows. If it says "The machine is permanently activated," your copy of Windows is genuine.

2. Check Product ID

• Open Settings (Press Windows + I).
• Go to System.
• Select About.
• Under Windows specifications, check the Product ID. Genuine Windows will have a valid Product ID.

3. Use Windows Activation Troubleshooter

1. Open Settings (Press Windows + I).
2. Go to Update & Security.
3. Select Activation.
4. If there are any issues, you will see an option to Troubleshoot. Follow the on-screen instructions.

4. Microsoft Genuine Advantage Diagnostic Tool

Microsoft provides a tool to check the genuineness of your Windows. This tool is no longer officially supported but might still be available for download from various sites.

5. Windows Genuine Advantage (WGA) Notifications

If your Windows is not genuine, you may receive periodic notifications from Microsoft informing you that your copy of Windows is not genuine. This can include a persistent desktop notification and restrictions on certain updates.

By using these methods, you should be able to determine whether your copy of Windows is genuine or not. If you find that your Windows is not genuine, consider purchasing a valid license from the official Microsoft website or an authorized retailer.
