The Get Windows 10 APP tells me I can't reserve a copy of Windows 10 because my CPU is not supported. Anyone know if this is actually true? The i5's are pretty much THE mainstream CPU, are they not?

Windows is fully updated and I already had the latest chipset drivers, but re-installed them anyway. Still says my CPU is not supported. I have no idea what the issue is. Could it have something to do with the Asus AI suite software having auto tuned my PC?
