How To Sign Up For Freebies Quickly?

I somehow have something installed on my computer that remembers all my info. when I sign up for all these free samples to where it only takes me literately about 10 seconds for each one because all I have to do it put in the first character for each field and it brings up my name address ect...  I don't know if anyone who reads this can help any other readers out there with how you can easily put this on your own computer to make signing up for samples really fast?  I do not know how it is on my computer, but I know it makes my life so much easier!  If you know anything about this please share!
