Problems after KB3213986 update - Microsoft Community

while the kb3213986 update getting installed experienced unusually long time message saying 100% of update done.

i waited , finished. after this, screen brightness shortcut keys not work. brightness slider appear when pressing keys slider did not move. moving mouse did not screen brightness.

i restarted , now, on top of that, taskbar items did not load. when run eg viber, appeared @ taskbar. start menu/button did not work @ all. 

i uninstalled update , went normal. after while got message update ready , install in non-working hours etc.

how can bypass update? there else can do?

my system lenovo g50-70 laptop.

after re-installed update, works fine. must have gone wrong installation first time around. i'll post again if gives me more trouble.
