Hello. I recently purchased a new laptop that came with Windows 7 Home Premium preinstalled, therefore it's a legitimate OEM copy. I want to upgrade it to 7 Ultimate. I assume I have SLIC 2.1? Because of this, is there any proper way to activate permanently without failing activation ever? I've used Daz's loader on other people's computers, but they do not have SLIC 2.1. Thanks!
