I appreciate your help, however, none of those worked for me.
The sfc /scannow window popped up for 1 second and was gone.
The next command would not create a window or the icon you said.
I tried the SURT...nada.
After reading some of the other issues, I finally went straight to Windows.com downloads, chose 1 update & downloaded Windows Update KB3102810
That worked! Once I downloaded just that one, off my laptop went to find more and download them itself. And its still working!
I am now current again! YIPEEE!!!!
