Currently, you cannot know automatically if a package works *only* on 
Windows (or whatever OS else). We have had this discussion before, and 
yes, it would be nice to have some additional DESCRIPTION field for 
OS/platform restrictions. But then it is difficult to have some unique 
identifiers and to get the information from the OS. And then people 
might want to do cross-platform stuff and so on.
