I use Surface pro for the first time and it run well and can update to 8.1 pro. The problem occur when I reset my surface pro I haven't see update to 8.1 from Windows store again. Everything that told from Microsoft website, I did it every update and it still not show 8.1 update. Later I noticed that in "Windows Activation" topic in System windows. Usually I saw from other computer that use windows 8 License Terms will show like this: But my surface pro shown like this: Anyone know about this message? This cause the problem of my surface pro cannot see 8.1 update on Windows Store? Thank you.
