There is a known incompatibility between Cygwin and interactive native 
Win32 console mode programs.  (e.g. regedit, ftp...)  The Cygwin 
developers know about it and are likely thinking about ways to fix it.

The trick is that the incompatibility exists in order to make Cygwin 
programs work better with each other.  Therefore, if you can find a 
Cygwin way to do what you're after, you will avoid these problems.

In the case of the registry, use either regtool(1) or /proc/registry:

That's the method I use, too.

The Windows security system is vastly more complicated than what you 
find on *ix systems.  Administrator really isn't equivalent to POSIX 
root.  The default Administrator login in Windows simply has a default 
set of capabilities that gives it a limited root-like set of powers. You 
can turn another user into an Administrator equivalent -- or a user with 
even more power! -- piece by piece.

Therefore, there won't be a single command that tells you if you have 
root-like privileges.  You'd have to test for the bag-o-features you need.
