Hello. This is my first post although I've been reading this forum for some time now. Usually with a sense of awe at the expertise on show and an envious wish that I had the same knowledge. As it is, I'm merely a novice with a very limited grasp of PCs although I have been able to teach myself how to do a few things e.g. I've updated my BIOS and installed one of the Win7 evaluation copies, things I could never have done before discovering forums such as this one. It's not always easy to get a full understanding of new topics such as 'SLIC2.1' and there are some things that I'll never understand but I'll have to live with that. Anyway, the reason for my post is that I need some clarification. I'm currently using Win7 Build 7137 which expires next March and will then, I believe, shut itself down every 2 hours. Now that the RTM is out, I'm downloading the links kindly provided by colinzim (http://forums.mydigitallife.net/threads/7954) My intention is to create a bootable DVD but NOT to install the RTM just yet. This is because: a) My current Win7 works fine. b) There seems to be a lot of confusion over which 'Loader' to use. c) I've read in another thread (http://forums.mydigitallife.net/threads/7986?page=8) that some people are waiting for OEM keys which they confidently predict will be leaked once Win7 is in the shops. As I understand it, you do not need to have a SLIC2.1 ennable BIOS when using a Loader. On the other hand, I believe that proper keys will only work with SLIC2.1. Is that right? It seems that there is no ASUS (my mobo) SLIC2.1 just now but my thinking is that, before Win7 goes on sale, ASUS MUST issue an update or there will be folk buying Win7 and not being able to install it. Does that make sense? So, by my own logic, there's no point in me installing RTM when I have a working Evaluation Copy. Better to wait for an official BIOS update and for a leaked key. Is my logic sound? Thanks to you all.
