Dell Inspiron 5559.   After doing a system reset, the laptop keep loop at the final setup (where you choose the language, etc). After some troubleshooting, I ended up creating a system restore and recovery flash drive and seemed to successfully apply.    Now the laptop boots into windows. HOWEVER, after the initial logon screen-- which I am unable to actually logon since it automatically uses ADMINISTRATOR, I am placed in an odd-looking windows desktop.   "prelogindell.jpg" " after restart, system automatically logs on as Administrator.  i am not prompted at all for pw. In th blurred background i an see the original desktop background. "aftera-auto-logon1.jpg": after the automatic logon as administrator, the desktop is not what's expected.  Any ideas? I'm certainly struggling here and cannot buy a new laptop.
