    Hi, I'm John!

    If your Windows 10 Pro retail license is genuine and currently activated, you normally do not need to purchase a separate Windows 11 Pro key. A Windows 10 Pro retail key can be used to activate Windows 11 Pro.

    1. Are you upgrading the motherboard, CPU, or the entire PC?
    2. Is your Windows 10 Pro currently activated?
    3. Is the retail license linked to your Microsoft account?

    If this is a new PC build, you can install Windows 11 Pro using a USB installer and then activate it with your existing retail key. If the license is transferable and no longer in use on another device, activation should work.

    Hi,

    If you have a genuine Windows 10 Pro Retail (USB/pen drive) license, you do not need to buy a Windows 11 Pro key. Your existing Windows 10 Pro retail key can be used to activate Windows 11 Pro for free, as long as your PC meets the Windows 11 hardware requirements.

    If you're moving to a new PC, you can transfer the retail license to it (retail licenses are transferable), but it should only be activated on one device at a time.

    Simply install Windows 11 Pro using Microsoft's official installation media and enter your existing Windows 10 Pro retail key during setup (or activate it afterward). There is no upgrade cost for a valid retail license.

    So, in short: You already have the license you need—just install Windows 11 Pro and use your Windows 10 Pro Retail key.

    Hi,

    You usually don't need to buy or obtain a separate Windows 11 Pro key. Microsoft allows a genuine Windows 10 Pro product key to activate Windows 11 Pro.

    If your Windows 10 Pro license is a Retail license, it can generally be transferred to a new PC (provided it is used on only one device at a time). In many cases, Windows 11 Pro will activate using the same product key.

    However, if the license is an OEM license, it is normally tied to the original device and is not transferable to a new motherboard or PC. OEM can only be used on the same motherboard that previously had Windows 10 activated on it.
