SWbemObjectSet does not have ItemIndex on some systems

SWbemObjectSet does not have ItemIndex on my system (windows xp).

I think you should use _NewEnum instead. But I am not expert.

ItemIndex doesn't exist either on Windows 2003. I'd really like to see this sorted.

This is pending https://github.com/go-ole/go-ole/issues/64 to be sorted as we want to call _NewEnum on the SWbemObjectSet to get the enumerator and then iterate over it. Means we shouldn't need to call the Count method to get the number of items as I've had issues with that on XP.

The issue go-ole/go-ole#64 has now been sorted so this should be fairly easy to implement now.

Hi, is there anything I can do to help? I know next to nothing about WMI internals but I can help test

Need to merge SokoloffA pull request, it solves this issue.

Should be ok to close this.
