Unlike the Windows 9x/ME series of operating systems, these new operating systems have very effective password security measures which you can use to protect your system and your data from unwanted access.
Of course, what happens if when you forget the passwords? Congratulations… You've just become "the enemy" as far as your computer is concerned.
Fortunately, for every method of password protecting a computer system, there is a method of defeating said protection, especially if you have physical access to the computer. Since it's your PC, that shouldn't be a problem, so cheer up.
In this guide, PCstats will explore the various methods that can be used to password protect computer systems, and how to defeat them if you lock yourself out. We'll start with non-user account related passwords, like the computer BIOS password and Internet Explorer passwords, and proceed on to methods of breaking into your system again if you manage to completely lock yourself out.
