Why Matlab doesn't use multiple cores on Windows server and on Win 7 does?

Dear all,
I have encountered an issue, in which, in Windows 7 MATLAB automatically uses all the CPU cores while in Windows Server 2012 it runs only on a single core (very low usage of the CPU). I have all MATLAB packages installed and run the same M-file. Is it normal? Any solutions for the problem?
Thank you in advance

How did you determine that in Win Server 2012, only a single core is being used? Did this affect the performance of your script? I mean, does your .m code run slower in 2012 than in Win 7?
There is a way to force an application to use certain cores by setting a property called 'CPU affinity':
Can you try this?

Could you please tell us how did you fix it in BIOS settings? We are experiencing the same problem. Thank you!
