If Microsoft expects its customers to take license agreements seriously, it has a responsibility to communicate the terms of those agreements to its customers clearly and unambiguously.[…] I’m talking about OEM System Builder licenses for Windows desktop editions. […] According to Microsoft, [those who] bought that software and installed it on their own new (or old) PC … are violating the terms of OEM System Builder license agreement, which says, in convoluted language, that you must install software using OEM Preinstallation Kit and then resell PC to a third party.
