Saw people saying they converted the WIM to ESD to save filesize, I just ask as I see a download online which has all the latest updates up to last week and 32 and 64 bit windows but I want to add at least the latest video drivers to the disc as well as my wireless card ones that dont normally come with integrated discs but worried that doing so will mess up the image or even if it works it will just convert it back to wim and create a massive file size. So will I need to convert it to WIM? or back to ESD when done? if so how? EDIT It should be Windows 7 ESD to Wim and back, I thought that was what I typed.
