Which fonts are missing? These should probably be added to the registry as part of their installation process.
fonts that exist in \windows\fonts before boot
i'll admit it's a bit of an odd case, but my windows 2012 r2 will install and record in the registry any new fonts added to \windows\fonts
the idea with my patch is that if new fonts are copied to Wine's fonts folder, it'll pick them up on the next wineboot and list them in registry
I realized my subject is misleading. i don't expect fonts i copy while Wine (or Windows) is running to be installed and show up in the registry (although copying using explorer on my windows box does install them)
