I have XP Pro. I am trying to install SP2, I know lots of people advise against this, I have found that I have a hacked Key. I know have a true product key and want to change the key on my computer. The problem is when I follow the diretions on http://support.microsoft.com/default.aspx?scid=kb;en-us;Q328874, I do not have the following subkey "OOBETimer'. What should I do?
