I'm not 100% sure, but in 95% I am, that my Intel Atom D410 (one core with HT) reported 2 CPU counts in Resources, and now I see only one. I do not know when it has changed - now I use MT 6.20. I have a "checkmark" at MultiCPU option in Resources/Hardware. Wiki says: CPU count=Number of CPUs present on the system. Each core is separate CPU, Intel HT is also separate CPU.
