I suggest what the Mac did going to OSX. They made OS9 run in a window. And they made dam sure the application developers did a bang up job with their OSX upgrades. People flocked to OSX because it was truly better, not in theory but in practice. Programs ran faster, OS ran faster, etc.
Perhaps Win7 as a virtual machine under Win8? Then support the application writers like mad to ensure no one ever wanted to run Win7 again. Microsoft has the $$ and know how. I hope they do it.

an interesting and informative read. I even forgave his ignorance that a 32 bit OS can address much more than 4GB of RAM because he got the rest pretty well.
