The SP3 / 4 / 5 meets all other requirements, TPM 2.0, Secure Boot UEFI, etc. Officially, the processor of the Microsoft Surface Pro 3 (SP3 / SP4 / SP5), is not supported by Windows 11. Yes, you can upgrade a Surface Pro 3, Surface Pro 4, or Surface Pro 5 to Windows 11. The “Registry Add Method” is still the easiest/quickest for an in place upgrade.

If this method doesn’t work for you, scroll down for info on the “Rufus” method, “AveYo’s MediaCreationTool.Bat” method, and “editing Windows 10 bootable USB” method. Update : The “Registry Add Method” instructions in this article are confirmed by Robert L and MOEJJ to be still working fine.
