This is for a W98 machine. None of your links are applicable except the very first one in #3. All the rest are for later operating systems.
The correct approach is to first establish which password the poster means. If it is after the Windows screen arrives then it can normally be sorted out quite easily. If it is before Windows even starts (BIOS) then there ways to clear this too. Third party software is not usually necessary and I doubt any of those suggested deal with a BIOS password.
pugman52, could you please try to determine which password you mean and we can then progress your post. Let us know exactly when the password request occurs It is just possible that it was put on by a company, in which case happykaka's first link might appy (assuming there is some way to run the software).
