Typed URL's deleting in 1day

I'm still trying to figure out the "setups" for locations of items in Vista.
When I type a URL (Web address in the "Address Bar") it will auto delete the
next day. I figured there might be a setting just for the length of time (or
quantity of typed URL's) it will stay (or hold) in the address bar when you
click the arrow rather than having to put it in your "favorites" and
accessing the website from there or having to retype the URL again. I have
my history files set for 22 days (I saw nothing else there), also I could not
find it in the registry where the "Typed URL's" are located either. If
someone could direct me to the location where I can adjust for items saved in
the address bar I would appreciate it. Thank you.
