I have a OEM computer preinstalled with Windows 7. So, its BIOS originally has SLIC 2.1, to facilitate OEM activation of Windows 7. Suppose that I have recently formatted the hard drive, performed a clean install of Windows 8 and activated it. And now, I want to remove Windows 8, and return to using Windows 7. The questions are: 1. After formatting the hard drive, can I still install Windows 7 and perform OEM activation of Windows 7? 2. Does the installation and activation of Windows 8 affect the SLIC 2.1 in the BIOS? Well, I just want to make sure that I can return to using Windows 7 anytime in the future. Thank you for your information.
If you have a modded bios with slic 2.1 added to help you activate win 7 , then first check your Bios and xrm-ms certificate wtih David's Slice tool kit 3.2 to see if every thing is in order. I had installed win 7 x64 and then installed office 2013. I activated office withg kmsnano 11. it activated both win7 pro OEM and office 2013 in to VL ! when I restored win7 image it got deactivated because slic2.1 wasn't matching the cert. I reflashed the Bios with correct info , then did image restore . you can go back and forth any time with Images.
