Hello, I have an ASUS G51Jx. I've just installed Windows 7 Ultimate on my laptop and used the latest ASUS OEM SLP key. I did the install certificate thing (ASUS.xrm-ms) but after restarting, Windows still says 30 days left to activate. However, when I used a Windows site to check if my OS is genuine, it says it is. Why is this happening? My laptop came with Windows 7 Home Premium, so I shouldn't need to mod the BIOS to get the SLIC 2.1 table in right?
