I purchased a manufacturer refurbished Vivotab Note 8 with 32GB. I've never owned a Windows Tablet and own an Android phone; so, Windows 8 is new to me. I have a few questions I'm hoping someone can answer. What should I do first? I downloaded a few apps; but, now I kind of want to back up and do all the things I need to do before going further. Should I do a backup of the system to an sd card first? This seems like a stupid question now that i've typed it but there it is. When i checked the device storage this morning it said: 2.5GB of 20.26GB avail. There is 700mb of apps. This seems wrong. 2.5GB? What am I missing? There is no music, no pictures, no documents on it yet. One last question: It has Office 2015 on it but when I tried to open it it acted as if I were installing...okay..that's fine except there is not enough memory left....any thoughts on that? I'm not sure what to do ...something seems off... Thoughts? Thank you for your help.
