MSDN  recommends  another approach. They say, that you should retrieve
the  value  of "System Up Time" counter from HKEY_PERFORMANCE_DATA. In
theory,  you  can do it without win32all, by using _winreg module. All
you  need  is  to  know  a  counter  index,  which can be fetched from
registry.  On  my  system "System Up Time" counter has index "674", so
Python code should look like this:

>>> import _winreg
>>> value, type_code = _winreg.QueryValueEx(_winreg.HKEY_PERFORMANCE_DATA, "674")
>>> print "Uptime: %s miliseconds" % (value,)

But in current implementation of _winreg it doesn't work. I've checked
the  sources  and  found  that  current  implementation doesn't handle
ERROR_MORE_DATA,  which  prevents  it  from retrieving any performance
counters. I'm thinking of bug/patch submission.
