In most cases, ordinary users don't have to pay for some necessary software for your system except you really like them or make a living on them. You can always find a good alternative software for commercial software. EX, Gimp - Photoshop, Openoffice - Microsoft office, Blender - Maya, 7-Zip - WinRAR, etc. And lots of free & open source softwares and games are waiting for you. So why you still want to buy a business software? And I highly recommend you have a try with Linux!
All the softwares here I share could be downloaded and used well, any cracked software won't appear at here. :)
