I need to reset the Administrator password on one or both of my computers. Both were purchased about 15 years ago. I am pretty sure that I am logged with administrator privileges on both machines. I am able to install and uninstall programs on both machines. But I haven't logged in as the Administrator since they were purchased.
I found this site that offers 5 ways to reset the Administrator password.
Are any of them valid? If so, which ones? If not, can anyone suggest the best way to do this?
