Hold on. I wrote '/drv/c/Windows/regedit.exe' (irrespective of its bit-ness).
BUT! See bottom of this message.

C:\Users\Henri> dir /tc /4 c:\Windows\regedit.exe # using 32-bits cmd
Volume in drive C has no label.
Volume Serial Number is 12F0-A5C0
Directory of c:\Windows

C:\Users\Henri> dir /tc /4 c:\Windows\regedit.exe # using 64-bits cmd
Volume in drive C has no label.
Volume Serial Number is 12F0-A5C0

Size and date/time of creation are the same.

For instance, here
http://msdn.microsoft.com/en-us/library/windows/desktop/aa384187%28v=vs.85%29.aspx
it said
Access to %windir%\regedit.exe is redirected to
%windir%\SysWOW64\regedit.exe (in case of
32-bits application)
The current situation on my W7 does NOT agree with the above statement.

Here it shows that 32-bits Cygwin "sees" (i.c. ls, stat) a different file at

Note:
- 32-bits Cygwin invokes 64-bits regedit in case of /drv/c/Windows/regedit
(yes, different from the one it "sees" (i.c. ls, stat) !!!!!
- 32-bits Cygwin invokes 32-bits regedit in case of
/drv/c/Windows/SysWOW64/regedit
- in case of /drv/c/Windows/System32/regedit: dito
- /drv/c/Windows/SysNative/regedit: does NOT exist!
(the 64-bits version only lives in c:/Windows)
