my computer is a blue screen requesting authentication code which I no longer have for windows 98

You could try searching the internet for a Windows 98 keygen.
Most sites are going to be full of spyware/adware I'm guessing so you might want to make sure you have some type of program for removing those things first.

bound to do that....got barred for doing it a while ago...plus this is your first question?...entraptment.

Do you mean you've lost the CD number, 25 digits?

IF so, Google 'Jelly bean', this is a windows serial keyfinder. Your anti virus may flag it as a trojan, it isn't, just run it.
