Windows 7 is the theme while I am away and thought I would share this little nugget with you.  Windows 7 has a lovely feature where it can mount and read / write VHD virtual hard disks.  Now this is good, but you can create one and install Windows 7 inside it.  You can then boot it up as normal, but it is portable at this point, so it is easy to backup, copy or examine on another system.

How to do this… well, look here - http://www.iishacks.com/index.php/2009/01/11/install-and-boot-windows-7-beta-or-windows-server-2008-r2-beta-on-vhd
