Powershell script to show Exchange Server 2010 build information

This is an updated version of the script that I wrote for Exchange Server 2007.  The new version works for both E2007, E2010 as well as environments where both versions coexist.

Ok, so the script is a bit messy and could use some polish – but, hey, it works for me 🙂

Watch out for two the lines beginning with $regKey.  They might wrap in the window here but should be on one line.  Note also that WordPress does something funky with the character codes and you may need to replace the double-quote characters if you copy/paste the code.
