I have a problem here and that is, I forgot my administrator account password. Can someone help me with tips on how I can log into my computer as an administrator without the use of administrator password. I have the guest account working but in there, I can't be able to install any softwares or do anything else that requires the administrative privilege. My machine is installed with windows xp sp3. I do not want to do a clean install because I feel that it is going to be time consuming and costly as well. Can someone help me please?
