The "mount.exe" program will run even if the mounts are all gone (as long
as it's invoked via an absolute path or from the current directory and
cygwin1.dll is in the same directory).

No, no, no, no, NO!
It's been stated time and time again on this list that going to the
registry is an unsafe and nonportable way of manipulating the mount table.
Especially when mount.exe does a very adequate job. There already are
plans (and code, AFAIK, though not in the production system) to store the
mount table in a file instead of in the registry. Please manipulate the
mount table only by using mount.exe (or setup.exe).

You can make a backup copy of the shortcut. You can, in fact, have
multiple shortcuts. This still doesn't avoid the fact that you cannot
have multiple versions of cygwin1.dll running at the same time (and even
having two different versions on the same machine is dangerous -- you'd do
better by renaming the old cygwin1.dll to old-cygwin1.dll, for example).
