Run more than one instance of REGEDIT

On Windows XP and Server 2003, REGEDIT takes a command line parameter that indicates a new instance should be opened up if an existing instance is already running.

REGEDIT -m (or /m) does the trick...

I assume the 'm' is for "multiple"...


Bart's Preinstalled Environment

This one's been around a bit I'm sure, but it looks pretty cool:
Bart's Preinstalled Environment (BartPE) bootable live windows CD/DVD
"It will give you a complete Win32 environment with network support, a graphical user interface (800x600) and FAT/NTFS/CDFS filesystem support. Very handy for burn-in testing systems with no OS, rescuing files to a network share, virus scan and so on."Haven't had a chance to try it yet. That could be a good thing, or a bad thing... :)



http://www.win.tue.nl/sequoiaview/ has a cool program called SequoiaView, but it hasn't been updated since November of 2002. It shows which files and folders from a specified base folder take up the most space using "squarified cushion treemaps".
