So, you’ve installed Windows 11 but keep seeing that annoying “Activate Windows” watermark at the bottom-right corner of your screen? Don’t worry—you’re not alone. Activation is essential because it confirms that your copy of Windows is genuine and unlocks all personalization features.
While most people activate Windows through Settings, another quick method is by using the Command Prompt (CMD). This guide will show you step by step how to activate Windows 11 using CMD in a safe and simple way.
Why Activate Windows 11?
Before jumping into the steps, let’s cover why activation is important:
- Removes the watermark that says “Activate Windows”.
- Unlocks personalization options like themes, wallpapers, and colors.
- Ensures security updates and full Microsoft support.
- Confirms your license is genuine and linked to your device.
Step 1: Check Your Windows Activation Status
First, confirm whether Windows 11 is already activated.
- Press Windows + I to open Settings.
- Go to System → Activation.
- Look under Activation state to see if it says Active or Not active.
If it’s already active, you’re good! If not, continue with CMD.
Step 2: Open Command Prompt as Administrator
You’ll need admin privileges to activate Windows with CMD.
- Press Windows + S and type cmd.
- Right-click Command Prompt and choose Run as administrator.
Step 3: Install the Product Key Using CMD
Now, enter your valid Windows 11 product key.
In CMD, type the following command:
slmgr /ipk your-product-key
(Replace your-product-key with your actual 25-character license key.)
For example:
slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Press Enter and wait for confirmation.
Step 4: Connect to Microsoft’s Activation Server
Once the key is installed, connect your PC to Microsoft’s activation server.
Type this command in CMD:
slmgr /ato
Hit Enter, and Windows will attempt to activate online.
Step 5: Verify Activation Status
To double-check:
- Press Windows + I → System → Activation
- Or, in CMD, type:
slmgr /xpr
If activated, you’ll see a message saying “The machine is permanently activated.” 🎉
Alternative: Activate with a Digital License
If you upgraded from Windows 10 or linked your Microsoft account, you might have a digital license. In that case, Windows will auto-activate once you log in with your Microsoft account—no CMD needed.
Troubleshooting Windows 11 Activation in CMD
If activation fails:
- Check your product key – Make sure it matches your edition (Home, Pro, etc.).
- Run CMD as administrator – Without admin rights, commands won’t work.
- Check internet connection – Activation requires online access.
- Run Activation Troubleshooter:
- Go to Settings → System → Activation → Troubleshoot.
Tips for Safe Activation
- Only use genuine keys from Microsoft or authorized resellers.
- Avoid pirated keys or shady activation tools—they can harm your PC.
- Link your Microsoft account to keep your license safe, even if you reinstall Windows.
Conclusion
Activating Windows 11 with CMD is quick, simple, and effective. With just a couple of commands—slmgr /ipk to install your product key and slmgr /ato to activate—you can unlock the full power of Windows 11.
Remember, always use a genuine product key to ensure your system stays secure, updated, and supported.
