As already mentioned, the font cache gets updated. This doesn't matter. If you absolutely cannot live with this, you can work on making the corresponding keys volatile.
Can you please shed light on that - I'm not into Wine internals at all.
You still haven't demonstrated a real problem, and trying to "optimize" for the case of an empty app that does nothing isn't particularly interesting.
Alexander, I guess 99% of Windows applications don't touch (write to) HKLM registry hive when running, so I think this bug makes a perfect sense for e.g. laptop users who would like to minimize disk thrashing.
