I work for a repair shop and we often get people who want a full wipe and clean OS install on their laptops. Most of them use Windows 8.0 and not 8.1 for some reason. One way or another Windows 8 key is embedded into their BIOS and we just try Windows 8 or Windows 8 Pro to figure out which Windows 8 they have. If we select the right Windows 8 version, a window that asks for product key during install will NOT show up. However, at times we do get 8.1 machines and customers are just un-aware of their versions. I can find and get Windows 8.1 AIO that includes updates up to September. But what about Windows 8.0 updated all the way to September? I've never seen a single version release like that, let alone AIO release of Windows 8.0 updated! Because of the embedded key version, we have no choice but to install Windows 8.0 instead of 8.1 on many machines. Having to go through INSANE number of updates after raw Windows 8.0 installation takes several hours. An updated Windows 8.0 AIO or at least stand-alone versions would be of HUGE help! Another question is - is there a tool that can detect version of Windows 8/8.1 product key? I don't need the key, but a tool that would identify the exact Windows 8/8.1 version embedded into system BIOS would be so awesome!
