What do you mean, you can't delete MS Internet Explorer, Davied? When you use the Windows Add/Remove programs, what happens? You should be able to install another version of IE, or even Netscape and browse with that if you want to.

In the worst case, you can completely reformat the hard disk and reload operating system and whatever programs you want. There's always a way to bypass whatever password might have been set up using the options in the BIOS. You can enter the BIOS setup by hitting a key when you reboot the machine, often the ESC or one of the Fn keys. Be sure you know what you're doing before you get into this, though [g].
