Does not lock account when daily time reached - windows XP

does anyone run WIndows XP?

Norton family says it locks the PC when the daily limit is reached, but it does not lock the account.

I am 100% sure becuase i can just carry on using it forever!

 

he can still log in during curfew times, and i read it gives you some time, then some more and finally locks you out, but i have not found this to be the case.
