I have a retail Windows 10 license linked to my Microsoft account, and I'm building a completely new PC with different hardware. Can I use that license to activate Windows 11 on the new system, or will I need to purchase another license?

The key distinction is retail versus OEM. Licenses that came preinstalled on a major-brand computer are normally tied to that original machine and won’t transfer. A separately purchased retail license, especially one registered to your Microsoft account, is intended to be transferable. Microsoft support may sometimes help with unusual OEM situations, but it isn’t guaranteed.
Yes. Since it’s a retail license linked to your Microsoft account, you can generally transfer it to the new computer and use it to activate Windows 11, as long as you’re installing the same edition, such as Home or Pro. During activation, sign in with the linked Microsoft account and run the Activation Troubleshooter if Windows doesn’t activate automatically. The license should only be active on one PC at a time.

Windows activation is strongly associated with the motherboard, but that doesn’t prevent a transferable retail license from moving to new hardware. The troubleshooter can help remove the old device and activate the new one.
