CoInitialize required in MFC app on XP but not Vista/Win7? - web-services

Question

I have written a SOAP Web Service that I'm trying to consume from an MFC application. The MFC application was not generated with ActiveX control support or Automation. When I run the MFC application from Vista or Win7, there's no problem accessing the Web Service. When I run the MFC application from XP (SP3), the Web Service call fails with 0x800401F0 CO_E_NOTINITIALIZED "CoInitialize has not been called". Calling CoInitialize(NULL) fixes the XP problem.
Why is the MFC app in XP behaving differently than Vista/Win7 in this case?
EDIT2: Auto-generated web service access code added

MFC Application created from VS2005 "MFC Application" template. All default wizard values except chose "Dialog based" Application Type and unchecked "ActiveX controls" from the Advanced features wizard settings.
The Web Service call in the code below (OnBnClickedCallWebWervice) works when run from Vista and Win7 systems. When run from an XP system, the call fails with CO_E_NOTINITIALIZED as the HRESULT. If I add CoInitialize(NULL) to the InitInstance method, the Web Service call works on all three platforms.
