Software Copyright Laws
I know you're wondering if you can buy the software and share it with your friends to save money. Though this may seem so easy to do, it is illegal unless otherwise specified on the software. Some software, like Microsoft Office for Students, will allow you to download the software on up to three computers, so always double-check.
