Hi Adrian_gw: Thank you very much for joining the Intel® Processors communities.
In regard to your inquiry the processor has no operating system restriction, meaning it will support the Windows® 7 Pro 64-bit version. However, the board where you are going to use the processor does have that restriction, so, in order to make sure if your platform will be compatible with that operating system just verify the motherboard compatibility list on the manufacturer’s web site and you will be able to confirm that information.
Any further questions, please let me know.
