A fresh install of 10 Pro on my laptop that was running 8.1 Pro isn't so great. Windows won't activate. It's telling me "Error description: The activation server determined the specified product has been blocked" Now here's the thing, I don't actually have a product key sticker on my laptop. It's embedded in the firmware -- I'm guessing since every time I've reinstalled 8.1 it activated without me having to enter any kind of product key. Maybe it's blocked because I ran the Release Previews on here? I don't know but I'm off to do a fresh install of 8.1 then do an in place upgrade with a USB stick. PS: Is talking to yourself against the rules here?
