I have recently modded my Award Bios of my motherboard Gigabyte GA-G31M-S2L to Dell SLIC 2.1. I would like to know which Company's SLIC would eventually support almost all past, present, to the future Windows OEM operating systems? (SLIC which is Best, Greatest, and valid for all OEM Windows especially recent Server operating system and their various editions). The one SLIC which is easiest to unlock latest versions of Windows, Windows editions such as Enterprise, Professional, Premium, Business, Server 2008, Server 2003, etc. Please respond with the best answer and I would like to try out that Company's SLIC. Thanks. With warm regards, Tushar.
