I purchased a computer from a company that went bankrupt and it is password protected, I would just like to wipe everything from it so we can use it. It has windows professional XP, but no backup disks.
[#0005ff]Not possible without buying a new valid copy of XP Pro, I'm afraid. Linux comes in many flavours and quite a lot of them are free to use. You could download a copy of PCLinuxOS 2010 from http://www.pclinuxos.com, burn it to a CD and run that CD as a live system using only RAM and be up and running in five minutes wit no Windows type driver issues.
Install from that and twenty minutes later you have a brand new, constantly evolving and updating Operating System with far fewer worries about hackattacks and viruses.
