I am backing up continuously to a separate external hard drive. I am using BitDefender Total Security. One problem that I am presently experiencing is with MS Windows Store. It no longer works. I cannot load or use any Windows apps. I have no idea what I did to cause this though it occurred a short time after downloading and installing BitDefender. After some internet search I found that I could open the Windows Store via WSReset. exe but none of the apps work. It is not a major problem. My Windows 8.1 now runs similarly to Windows 7. I can still find most of the applications or programs I want but not via Windows Store. It is mostly just annoying.
