Yes.  Cygwin will not process paths that contain a ":" -- perhaps
erroneously, as it should probably check that the ":" is the second
character, preceded by a letter.  <http://cygwin.com/acronyms/#PTC>.

Yes -- submit a patch to Cygwin. ;-)

Seriously, though, the /proc/registry handler does not support write
access to the registry.  The above is a standard disclaimer, though I
believe whoever put this in the description of /proc/registry was a bit
overzealous.

FWIW, if you want to use Cygwin tools to manipulate the registry, you can
use 'regtool'.

HTH,
