This can be done now,
That appears to contradict what you wrote yesterday:

You did mention
] HKLM/Software/Cygwin/setup, the "rootdir" value.
But you noted that that is in version 1.7.
(When mentioning it, by the way, you might also mention REG.exe, a
program to do registry access, and the options for FOR that allow
running a program and getting the results in a variable in CMD.exe.
I hadn't heard of REG until I went searching just now.)
