There is a C# solution here .

In summary, you need to loop through all processes ( Process.GetProcesses ) and set their .ProcessorAffinity to New IntPtr(1) , then start your new process. (The default is already to use all cores, but for completeness, if you want the new process to have a different affinity, set it after it's been started the same way as above.)

All the code:

Dim procs = Process.GetProcesses
For Each p In procs
 p.ProcessorAffinity = New IntPtr(1)
Next
Dim myProc = Process.Start("notepad.exe")
' Stop here to answer the OP.
' This sets the new Notepad process to be the only process running on the second CPU:
myProc.ProcessorAffinity = New IntPtr(2)
