Not really hard to do considering theirs like a million keygens for winzip and hardly ever expire, also 7zip that's totally free and just as good as winzip not much point to this service unless keys are 100% legit and can be confirmed are legit though winrar support
That's very true but thisisn't a keygen. I see where you're coming from though. These codes are 100% legit.
lol who pays for winzip
Well I wasn't sure I was just trying to help people out, sorry sir.
