Windows 7 Professional for older PCs
Windows 7 Professional is still used on older PCs, legacy software setups and offline machines. KRBKeys offers a genuine Windows 7 Professional key that works with both 32-bit and 64-bit installations, delivered by email together with the official ISO download link. Windows 7 Pro supports domain join, Remote Desktop, XP Mode and up to 192 GB of RAM on 64-bit systems.
Please note that Microsoft ended all support for Windows 7 in January 2020, so it no longer receives security updates and should not be used for online banking or sensitive work. For a supported system on compatible hardware, consider Windows 10 Pro or Windows 11 Pro.
