I might purchase cheap legit copy of unused Win8 OEM key that came with Dell laptop where owner instantly formatted it with Windows XP. The key is unpacked and never been activated, unless by factory setting. Those laptops have no sticker nor anything so I guess the original OEM key is embedded in BIOS. Is is the same as in the package? Just google something like "W8P 32/64BIT SVC DPK" to see, there's a 25 digit key there. Or is this pack key just generic OEM one that can't be activated? Also I might have probem with getting ISO, as Microsoft for some reason pulled down every Windows 8 link and replaced it with Windows 8.1. But 8.1 is not 8, and everyone who had both knows it. I could technically get those Dell installation DVD's that came for laptop but again I heard those will only work with this specific laptop because they are made this way. Could getting proper Windows 8 Pro System Buileder OEM iso and then using it with edited PID.txt work? Would such installation be legit and would it activate properly? Would it later freely update to Windows 8.1 and 10? My machine ain't Dell btw, just generic PC. Cheers, waiting for answers.
