I was using the "Windows 8 Upgrade Assistant" to see if I could upgrade to Windows 8. After doing so it found 4 Problems, 3 Don't worry me, but 1 does. It says "Your processor doesn't have NX turned on or might not support NX" So I checked my BIOS settings and found "XD" I don't know what it means but, Does this have something to do with "NX" or can I not make the Upgrade???
"Intel markets the feature as the XD bit, for eXecute Disable. AMD uses the name Enhanced Virus Protection. The ARM architecture refers to the feature as XN for eXecute Never; it was introduced in ARM v6."
