Windows 10: Reactivate with Windows 10 Key used before

I recently formatted a SSD and reinstalled Windows 10 on my desktop. Then I cannot activate the Window with the product key I used before.Could you help me for this issue?

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Product Key Reactivation

Hi

Thanks for your reply.

Reactivating Windows 11 after retrieving the motherboard key involves using the original product key or digital license associated with your system.

Here are the steps to reactivate Windows 11:

1. Open Settings:
   
   • Click on the Start button and select the gear icon to open "Settings."
     
2. Navigate to Update & Security:
   
   • In the Settings menu, click on "Update & Security."
     
3. Go to Activation:
   
   • In the left sidebar, select "Activation."
     
4. Enter Product Key:
   
   • If you have a product key, click on "Change product key" and enter the key when prompted.
     
5. Use Digital License:
   
   • If your Windows 11 was linked to your Microsoft account, you might see an option to troubleshoot and link your digital license. Click on this option and follow the prompts.
     
6. Restart Your Computer:
   
   • After entering the product key or linking your digital license, restart your computer.
     
7. Verification:
   
   • Go back to the Activation section in Settings to verify that Windows 11 is now activated.
