I'd note that Windows sets the volatile (what i called transient)
entries at startup. For Wine though, startup time is always an issue, so
yeah I'd think it makes sense to trap key not found errors.

Thanks, I took a look at this, seems to do the trick nicely.
Of course, now I'm wondering exactly what part of the registry code I
should use. Either:
a) In advapi32
b) In ntdll
The wineserver seems the most logical choice, but I'm not sure if there
are any special rules regarding it, nor whether Alexandre would accept
stuff like interface probing into the server, it might be considered
bloat. Care to comment Alexandre? Which is the best place for this code?
