I don't know the M$ API and only the fact to have to look at the Microsoft Developer Network gives me feels of having done something really nasty in my previous life :), but this seems to me what the isSunVM() does in the windows launcher, only it uses the windows registry to get information about the installed VM. Now, I think that parsing the jre/LICENSE file could give a good guess about the VM we are using. The alternative to the invocation API could be to hack around "buildCommandLine" or "launchJavaVM" (but I don't know the order these functions are called, so this may be too late), calling a small app that tell us java.vendor, and go on with the result of this query. That would solve for every other java provider, not only Sun, but at the cost of having a small "pathfinder" application added to eclipse...
