I have a dual processor system, each processor supporting 8 threads, so the OS should report 16 cores, which Linux does. But Windows shows just ten of them (even the 64-bit version). Six cores were reported as "not recognized" in the device manager. What does this mean? Do I have to install Windows Server to use them?

Sorry, I din't mention that I actuall have the 64-bit version installed. As for the link you have posted: it is a dual-processor system (not dual core) – artistoex – 2014-02-10T12:37:00.610
Probably a silly question, but when you go into mscongif>boot>Advanced Options. See how many cores it's using in there. By default your system should be using all the cores. – Matthew Williams – 2014-02-10T12:43:39.507
You can also go have a look how many cores are booting in Boot Configuration Data. Apologies I have no idea how to use this structure since it changed from the boot.ini. Sure a Google search will help you here. – Matthew Williams – 2014-02-10T12:48:27.477
Problem solved. After restarting the third time, Windows now recognizes all cores. – artistoex – 2014-02-12T19:51:23.717

Windows 7 supports between 32 and 256 cores. Windows 7 System Requirements

1You asked a simple question. What is the processor core limit on Windows 7 Professional. The answer is between 32 and 256 cores. You really didn't provide enough information to diagnose the problem itself. – Ramhound – 2014-02-10T12:49:59.803
