It is a known fact that Windows 11 is a free upgrade for eligible users of Windows 10. Windows 10 PCs that meet the minimum hardware requirements for Windows 11 can be upgraded to Windows 11 for free.
Some users who were looking to upgrade to Windows 11 from Windows 10 are asking if a product key is required or if a product key is required when upgrading from Windows 10 to Windows 11.
Do I need a product key to upgrade to Windows 11?
The answer is no. Users who have upgraded from an activated copy of Windows 10 do not need a product key to upgrade to Windows 11. While upgrading from Windows 10 to Windows 11, you will not be prompted to enter the 25-digit product key.
Your Windows 10 license will be automatically transferred to Windows 11 and your copy of Windows 11 will be activated automatically in the background. Therefore, you don’t need to do anything to activate Windows 11 after an upgrade from Windows 10. However, if you want, you can check the Windows 11 activation status to make sure your copy is activated.
That’s why it’s a good idea to make sure your copy of Windows 10 is activated before you upgrade to Windows 11. We recommend migrating your local account to a Microsoft account (if you are using a local user account in Windows 10) so that you can link your Windows 10 license account to Microsoft account. This ensures that you will not experience any activation issues after upgrading to Windows 11. After successfully activating Windows 11, you can revert to a local account if you wish.
Do I need to enter the product key after upgrading to Windows 11?
Again, the answer is no. When you upgrade from an activated Windows 10 installation to Windows 11, the new Windows 11 installation is activated automatically. Therefore, you do not need to enter the product key even after an upgrade to Windows 11.
However, if for some reason Windows 11 doesn’t activate automatically, you can enter the product key (if you have one) to activate your copy.
