Wc3 probably doesnt run when your not admin because you installed it when you were admin
Uninstall it with an admin account and then reinstall it with a non admin account and it should work fine
Unless your dad set it up to not allow non admins to install stuff
The password shouldnt have been effected
Im not sure why it would be
But if it happened once then it might happen again
He will also notice the new admin account if he watches the users, so youll probably be caught immediately
You can just use his account with
http://ophcrack.sourceforge.net/Dl the live cd version
Burn the iso to a disk with any iso burning software
Put the disc in the comp and boot from it
Follow the instructions and do what it says
Read the nt pwd field for your dads user name
Write it down
Turn off the comp
Turn it back on and take out the disc and let it start up normally
Use the password you wrote down with your dads account to use his account
You can keep reusing the disc if he changes the password, but he probably wont notice or suspect that you have his password unless your stupid when on his account and install something directly to his user name
It works with any modern windows based computer
Your supposed to use it to recover your own lost password, so what i said above about getting your dads password is only hypothetical and
shouldnt be done
I take no responsibility for what you actually use it for
