	import win32pdh
	def get_processes():
	 win32pdh.EnumObjects(None, None, win32pdh.PERF_DETAIL_WIZARD)
	 junk, instances = win32pdh.EnumObjectItems(None,None,'Process', win32pdh.PERF_DETAIL_WIZARD)

	 proc_dict = {}
	 for instance in instances:
	 if proc_dict.has_key(instance):
	 proc_dict[instance] = proc_dict[instance] + 1
	 else:
	 proc_dict[instance]=0

	 proc_ids = []
	 for instance, max_instances in proc_dict.items():
	 for inum in xrange(max_instances+1):
	 hq = win32pdh.OpenQuery() # initializes the query handle
	 try:
	 path = win32pdh.MakeCounterPath( (None, 'Process', instance, None, inum, 'ID Process') )
	 counter_handle=win32pdh.AddCounter(hq, path) #convert counter path to counter handle
	 try:
	 win32pdh.CollectQueryData(hq) #collects data for the counter
	 type, val = win32pdh.GetFormattedCounterValue(counter_handle, win32pdh.PDH_FMT_LONG)
	 proc_ids.append((instance, val))
	 except win32pdh.error, e:
	 #print e
	 pass

	 win32pdh.RemoveCounter(counter_handle)

	 except win32pdh.error, e:
	 #print e
	 pass
	 win32pdh.CloseQuery(hq)

	 return proc_ids
