import win32pdh import time while 1: dummy,processes = win32pdh.EnumObjectItems(None,None,'Process', win32pdh.PERF_DETAIL_WIZARD) print "LEN",len(processes) time.sleep(3) I create new processes, but the return still the same. Why this give always the same number of processes ??? (I'm on a W2K with Python 2.1)
