No, this box is Windows-free! The point is that installing applications
sometimes adds important keys into the .reg files, and some games refuse to run
unless these keys are present.

No, applications install their own registry entries too... (Obviously). And
that's "mandatory" as in "Wine blithely assumes that these registry keys exist,
and will core-dump if they do not.".

One man's "cruft" is another man's "crucial installation entry"...

As I suspected, you are completely neglecting what happens when people upgrade
Wine. And *everyone* upgrades Wine, and *no-one* reinstalls all their
applications each time either.

> $ mv .wine .wine-save
> $ wineprefixcreate
> $ test app
> $ mv .wine-save .wine

> voila!  Your old apps are back...

Yes, but along with the *old* .reg files, which presumably don't contain the
latest "mandatory / Wine-will-crash-unless-they-are-present" keys. So how is
that helpful? And trying to test my app doing what you've described above
doesn't work *precisely* because all the "cruft" is missing from the
newly-created .wine directory, and so the game flat refuses to run.

So, please tell me: How are all we millions of Wine users supposed to update
the .reg files in our .wine directories with the latest "must-have" keys,
whenever we upgrade to the latest version of Wine?
