A Fistful Of Password Busting Tools for Your Travels

If it's Windows you're after, don't forget about trying the easy way first. Reboot, hold F8 down, and boot to safe mode. Log in as Administrator with a blank password. It works on a scary number of systems, and you'll be able to clear or change any other password on the system.
Don't get too paranoid, Windows users. Removing passwords on other systems really isn't all that hard either.
Now, on to the tools!
Offline NT Password & Reg-Editor. There's an excellent walkthrough on the site, including instructions on writing the image to floppy, CD, or a USB drive. Works on almost all versions of NT, from 3.51 right up to Vista. Some success has even been reported on 2008. It's also included on Ultimate Boot CD.
PING. One of my favorite drive cloning apps also includes a utility to blank Admin passwords. It's a great disc to keep in your technician's tool kit.
Ophcrack. Runs on OSX, Linux, and Windows and uses rainbow tables to crack Windows passwords. Several tables are available for download, ranging in size from 380mb to 8gb.
Don't forget Nirsoft for Windows application passwords. Their apps will help you find Messenger, Mail, Dial Up, Firefox, Internet Explorer, and several other passwords, as well as wireless keys.
What about Mac? Grab yourself an OSX boot disc and read up. This article takes you through the process step-by-step. Linux users that need help resetting root's password can read this one for help.

With Halloween fast approaching, it's a great time to get in some practice defending your territory against zombies. In Graveyard Shift, you take aim at zombies and other creepy-crawlies, blasting them into splatters of cartoony green guts. It's a casual first-person shooter, and it's very easy to get the hang of - use the mouse to aim, click to fire. Graveyard Shift has at least 15 levels, and it might even have some secret stages I haven't unlocked yet.
They key to getting good at Graveyard Shift is learning to use ...

Just a heads up about the old boot-into-safe-mode to use the admin account trick; if you boot regurally and are not looged in to any user (switch user wont do it) then press Ctrl-Alt-Del twice to have the option on %99 of computers (and every one without an admin password) to type - not press - a username and password.
So just press Ctrl-Alt-Del twice, type "Administrator" and leave the password blank. Saves some time - especially on old systems.

Keep in mind that the Administrator isn't allowed to log in that way by default on XP or Vista...But it'll work in safe mode.
