If, when playing a video you get a message to download flashplayer but you already have it, do this. I found this cure on another forum.
Go to c:/windows/system32/macromed/flash. Click on and run FlashUtil9b.exe.
This solved the problem for me.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
