Your Windows login password (assuming you have one) is probably very easily cracked, and now you can test it. Lifehacker has an article on Ophcrack Live CD which is software you burn to CD and can then use to crack a Windows XP login password.

Now assuming your password is less than 14 characters, your password is easy pickins’ for this useful utility. For those of you who cringe at the thought of remembering a 14 character password like J490fhwe#.45Er, how about your start with something with 7 and a few numbers and upper/lower cases (I’m sure it will be better than “password” or “fluffy”)
