Extending Time limits of Programs

I'm not sure if its possible, but does anyone know how to extend the time limits of demo programs?

Try setting the date back on the windows clock.

Thats illegal, and make sure the program is off before you set back the clock, I have an example of how to find out if somebody just changed the windows clock(its in a book and it uses sublcassing).

I would recomend you buy the retail program.

or... SEARCH ALTAVISTA.COM fir the crack... or if you need I can get you a serial number, just post the program and version
