Windows 10 does allow certain hardware changes without affecting the license. These might include adding or changing drives, memory, video card, etc. By the same token, a major hardware change such as upgrading the CPU might result in license issues regardless if it is even after a new install. There is also dependency on the Windows 10 (and other versions) license type. Retail versions of Windows 10 present the least activation issues with hardware changes including uninstalling from one computer system and newly installing on a different computer system. On the other hand, the OEM or system builder Windows 10 license is more restricting. Should remote re-activation fail after a change, the fallback position is to contact Microsoft for a manual solution.
