Hello Tunga,

I'm not a Windows user myself (so I can't verify this is how Windows Task Manager expresses CPU usage), but this is my guess:

1) The total processor power available to you, given a Core 2 Duo, is X
2) The power of one of those two processors is then X/2
3) Stata/SE can only use one processor at a time (given it isn't Stata/MP)
4) 50% is actually Stata/SE using the full power of one of your two processors

Might that be the case?
