Double-clicking on the Cygwin launch icon brings up the window as
expected, but hung before the prompt appears, with the blinking cursor
indicator at the top left of the window.  ^C has no effect.  Clicking
the window's close box causes the cursor blink to stop and the window
to hang entirely.  After a few seconds, Windows brings up the "Windows
cannot end this program" dialog, at which point "End Now" kills it off
successfully.

While the window is visible but hung, there are three bash.exe and one
sh.exe process running, according to Task Manager.  All four of these
processes go away after I click "End Now."

C:\cygwin>cat /etc/postinstall/01bash.bat*
@echo off
rem Bash postinstall script.  Since setup.exe 2.457.2.2 insists on using
rem /bin/sh, and .bat scripts don't know about cygwin paths, this is a
rem two-stage install: /etc/postinstall/00bash.sh updates this script, then
rem this sources the real /etc/profile.d/00bash.sh with bash.  setup.exe
rem 2.510.2.2 and beyond use /bin/bash, so in 2007, it might be time to swap
rem back to a single postinstall shell script, instead of the .bat hack.

For "you" meaning "setup.exe and its subprograms," I assume.  :)

(Background here: I installed cygwin a year or so ago and have been
using it reliably since.  It occurred to me that I might want to take
advantage of a year of updates, so I downloaded the current setup.exe
and ran it, expecting the usual patch/upgrade outcome.  Alas, it was
not to be....)

(Repeated several times, as you can see; once per repeat attempt to do
the install.)
