I’ve had this question from more than one Windows tablet user like Brian from Ireland, “I have a Surface running windows Rt 8.1. What is Microsoft’s position re upgrades? Windows 10 etc?”
I’m afraid I have bad news for you, Brian. The RT operating system is not available for upgrade to Windows 10. First of all, a device built for the RT system probably couldn’t handle the system requirements for the full Windows 10 and secondly, Microsoft has given up on the idea of the RT OS and is now installing full versions of Windows on its tablets.
