Hi guys, I may add a bit to this conversation. Sometimes simple measures 
may do the trick, for example for a ContourPlot:


this gives a graphic that cannot be handled in the EMF vector format 
that is used by copy/paste on Windows.
However, it turns out that the only problem is the use of the Opacity 
directive automatically used for the contour lines.


will give you a graphic that does Copy/Paste as a vector format. In this 
case it is not even necessary to remove Tooltips (using 
Tooltip[a_,__]:>a), but it may be in other cases.

Ok, the result looks slightly different (lines a bit blacker), but that 
may be compensated by changing the ContourStyle.
In fact, choosing an explicit ContourStyle->{GrayLevel[0.2]} prevents 
the whole Opacity issue.

Looking at the InputForm of other graphics may give you more clues as to 
which parts should be removed before copy/paste.

Best wishes,
