What's the point showing that option in configuration then? If you do not support it, don't display it, very simple.
The only reason winecfg has all the windows versions list is for picky applications which require some particular windows version to see. Does QIP require Vista, or you just think it will work better if Wine reports Vista to QIP?
Otherwise, if you are really going to support that OS emulation, don't ignore problems.
There is no any change in Wine behaviour implied by the version change, Wine just reports a different windows version to the application, and that's an application who really may change its behaviour/used API coverage.
