If you see the “Windows 11 Not Activated” watermark on your screen, it means your copy of Windows is not properly activated. This watermark can be distracting and limits some customization features.
Activating Windows 11 ensures you get full access to updates and personalization options. Fixing this issue is usually straightforward and can be done with a few simple steps.
In this guide, we will walk you through the easiest methods to remove the watermark and properly activate Windows 11. No technical experience is required.
Follow along carefully, and you’ll have your system activated in no time.
Quick Note: Before You Begin
- Make sure your PC is connected to the internet. Activation requires online verification.
- Check if you have a valid Windows 11 product key. This key is essential for activation.
- Know which edition of Windows 11 you are using (Home, Pro, etc.). Activation keys are edition-specific.
- If your PC came with Windows 11 pre-installed, the activation key might be embedded in the hardware.
Step 1: Check Your Activation Status
Before trying to fix the watermark, verify if Windows is actually not activated. Sometimes the watermark appears due to other reasons.
- Click the Start button and select Settings (gear icon).
- Go to System and then click Activation on the right pane.
- Look under Activation state. If it says “Windows is activated,” your watermark might be a glitch.
If it says “Windows is not activated,” proceed to the next step.
Step 2: Activate Windows 11 with a Product Key
This is the most common method to remove the watermark. You need a valid product key for your Windows edition.
- In the Activation window, click on Change product key.
- Enter your 25-character product key. It looks like this:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. - Click Next and follow the prompts to activate.
- Wait a few moments. If successful, the watermark will disappear.
Why this matters: The product key verifies your copy of Windows and enables full features and updates.
Step 3: Use the Windows Activation Troubleshooter
If your key is valid but Windows still won’t activate, the built-in troubleshooter can help fix common issues.
- Open Settings > System > Activation.
- Under the activation status, click on Troubleshoot.
- Follow the on-screen instructions. The tool will detect and attempt to fix activation problems.
This tool is helpful if your hardware has changed recently or if there are temporary activation server issues.
Step 4: Activate Windows via Command Prompt
This method is for users comfortable with basic command-line tools. It can refresh the activation process.
- Press Windows + S, type
cmd, right-click Command Prompt, and select Run as administrator. - In the Command Prompt window, type the following command and press Enter:
slmgr.vbs /ipk YOUR-PRODUCT-KEY
ReplaceYOUR-PRODUCT-KEYwith your actual product key. - Next, type:
slmgr.vbs /ato
This command forces Windows to try activating online. - Close the Command Prompt and check if the watermark is gone.
These commands manually install your product key and trigger activation.
Step 5: Reinstall Windows (Last Resort)
If none of the above methods work, a clean reinstall of Windows 11 might be necessary. This fixes deeper system issues.
Before reinstalling:
- Back up all your important files to an external drive or cloud storage.
- Have your product key ready.
- Use the official Microsoft Media Creation Tool to create a bootable USB drive.
Reinstalling ensures a fresh system and can resolve activation errors caused by corrupted files.
Alternative and Advanced Options
- Digital License: If you upgraded from Windows 10 and had activation linked to your Microsoft account, sign in with the same account, and Windows might activate automatically.
- Contact Microsoft Support: For activation issues related to hardware changes or license transfer, Microsoft support can assist in reactivating your copy legally.
