Hi everyone, I've been following the site for a while but never registered. But today I got a great deal. Got a second hand SP3 I7 256Gb with a dock and keyboard at a very attractive price. So I bought it. And it looks class. All I hoped for really. A bit about me, I leave in Ireland and got a the SP3 for photography. A new bobby of mine. Started using PhotoShop and thought it would be great with the pen. Do a bit of light video editing and a lot of web browsing. Lol. Nice to have such an active community around. Now the guy I bought it from didn't reset it. Will I need a windows activation key if i do a factory reset?
