I bought my Surface first gen two days ago from an employee from a local retailer, who has won the tablet because of his job. So when I bought it, it came with a preconfigured account MMS on it. I think this would be deployed as demo item, but it never was done so.
So, the point is, when I checked This Computer there was a DVD-RW drive connected, with something like a install disk/iso from Windows inserted. Ofcourse Surfaces don't have physical drives, so I quicly copied the complete contents to my pc.
So my question: is this really the Windows RT install disk? I have really no idea how I can check that.
Quick edit: tried opening the setup.exe, and it popped up as Windows Server 2012.. That doesn't make sense at all, why would you have Server 2012 on a brand new Surface RT?! The Autorun.inf also said AMD64.
