WSH is common on Windows machines with VBScript and Jscript as standard

I think you may be confused here between the old DOS command prompt and
the real shell that comes with Windows NT/Windows 2K and Windows XP.
These all have similar functionality to bash with regards to 2> and 2>>

With 'start' it depends what you're starting. If you start a windows app
then there is no cmd shell hanging around. If you start a console app,
you get the console for that app, with no extra command shell. Isn't
this what bash does with & ?

Yes it does, try it.

For example I use an IDE called IDEA under WinXP. This has a batch file
to start the IDE. By default the batch file calls java with a bunch of
parameters and leaves a console window lying around. I've modified the
batch file to 'start javaw' with a bunch of parameters, now I have no
extra windows,
