(For Windows software, obviously.)
There used to be a lot of these around years ago. You would get a trial or shareware software title from its original source, find the crack/patch/keygen/serial that goes with it, do the needful, and use it to its full potential.
But all the crack/patch/keygen/serial search engines I knew seem to have shut down. Are any of them left? Where do people get cracks/patches/keygens/serials these days?
I don’t have an answer for you but this woke up an old memory of me sitting on my old ass XP machine running Serialz2k or whatever the shit it was called, big database of serial codes, username/passwords, etc for tons and tons of different software. Could update it monthly/quarterly and get new serials added into the database. Only managed to get a handful of serial codes to work but for a young teenaged me it was glorious.
There’s gamecopyworld for game cracks, I’m not sure about general software though.
I only know of GameCopyWorld and MegaGames for cracks.
I don’t know about a single reputable serial/keygen site unfortunately.
