Comment (by andysem):

 I took a look at the WMI code and noticed that in a few places you pass
 wide strings to COM methods. Strictly speaking, this is not correct
 because COM methods accept BSTRs, which are binary incompatible with wide
 C strings, unless the method implementation treats them as wide C strings.
 In particular, if it calls SysStringLen on the argument, the result will
 be undefined.

 FWIW, from [http://article.gmane.org/gmane.comp.lib.boost.devel/208308

 this thread] it seems that using WMI has its drawbacks, let alone the
 complexity. Perhaps, using performance counters would suffice?
 [http://www.osronline.com/showThread.cfm?link=10513 Here] I found an
 example of reading a few system counters, of which
 "\Process(System)\Elapsed Time" might be what you need. I did not dig deep
 into the code enough though, so this may be of little help to you.
