For example, there are a lot of legacy applications out there whose help documentation is in CHTML files [0][1] (*.chm). The CHTML viewer uses IE (unsure of the exact version.... maybe 6?). I can't imagine this going completely away any time soon, so I suspect that the dlls will still reside somewhere in the OS for a long long time to come.
Off hand, the Help for WinMerge is leveraging this framework [2].
Edit: I also think that the rendering engine of Outlook uses some legacy version of the IE html/js engines. Again, it might be 6... (maybe not)
