In preparation of my upcoming class in PhP, I was installing xampp 1.7.4 in an older laptop (running XP) and all was going well. The welcome page came up fine, then I went into the 'security' tab. I was baffled when the screen was asking me for the current password in the MySQL section? but I must have done something terribly wrong because now when I type http://localhost in the browser I get a 401 error and Authentication required. So I am stuck. Should I uninstall it all? and then start again? but where is the password?
