Where to find Win 11 Key for REinstallation

Hello, I have just received my brand new laptop Dell Vostro 7620 with Windows 11 Preinstalled. So I installed and activate Windows 11. Everything works just fine. In fact, that several applications are preinstalled (McAafee, Office 365, One drive, Dell Apps ...) and of which I have no use, I intend to reinstall Windows 11 from scratch. I would like to know, can I reinstall Win 11 Pro and activate it with that recovered key? In that case, as the Product Key would be embedded in the UEFI Firmware chip, how to recover it for Win 11 Pro Reinstallation? BTW, is there a utility to find the Product Key? I tested ShowKeyPlus, it doesn't help I'll appreciate yr help Regards

 

Reinstalling Windows 11 with the help of Windows 10 OEM Product Key

Hi, I am Dave, I will help you with this.

Rest assured, if you have pre-installed Windows 10 on that laptop, you have an OEM key stored on the motherboard, the upgrade to Windows 10 is still free so you can create a bootable USB to clean install Windows 11, skip the steps to insert a product key during the installation and Windows will self-activate.

   • 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.
