The idea behind shareware is being able to try software, then buy it if you like it. 'Unlocking' the software using hacks/cracks, obtaining serials, etc is not only wrong but illegal as well. Thus, this thread is locked.

P.S. If you're not willing to pay for Winzip, look to freeware options such as 7-Zip. With so many free, legal alternatives there's no reason to pirate.
