This tweak will allow you to open Cygwin via right click. No registry edit is required.
Assuming that you have installed Cygwin already.
On Win 7:
1. Download Cygwin Setup.exe and install chere package.
2. Right click and Open Cygwin as Administrator.
3. type "chere -i" or "chere -i -t mintty" if you would like to use Mintty which I personally prefer.
