I recently helped a friend turn off the login password on her Windows 8.1, HP laptop. The next time she went to turn it on, all the normal tiles from the Start Screen were gone with the exception of five tiles: IE, File Explorer, Store, SkyDrive and Desktop.
The File Explorer icon opens a folder showing the various libraries and devices/drivers. When she clicks on the Documents folder it doesn't show any of her files. I did eventually find them by going to her name in the Users folder, but we cannot understand why simply taking away the requirement for a login password would change everything. All her browser favorites were also wiped out, and she had to reinstall Chrome. I'm not a Windows 8 person (nor am I any kind of trained anybody...just someone trying to help a friend), so I'm not sure how to restore everything. Please help...
