Less than a month after setting this up, received a blue screen this morning AND one of the USB ports mangled our mini router when we removed it, so not only bizarre but also more $ down the drain.  No OS backup disk, while the Microsoft Office 2016 software is trial version - which we found out AFTER contacting the seller as this detail is not mentioned on their Amazon web page.  Meaning you will need to buy if you don't already have MS Office, while opening and switching existing Excel/Word documents back to an earlier version of MS Office can be tricky.  Also bluetooth functionality is missing despite going to Device Manager then installing and running Windows Updater.  You may want to purchase a PC from someone else who does more than state "sorry for any confusion" instead of helping after omitting that certain integral items will be missing from the box and selling defective equipment.
