sfc /scannow does not work.
I don't want to start a clean installation of windows I dont have time for that.
When I double click a movie, there's a pop up saying: "windows media player is not installed properly and must be reinstalled. Do you want to install the player from the Microsoft website?" But if I chose "yes", I get redirected to the website but there's a message: " There is no download available for this operating system. Please visit Windows Update
to check for the latest Windows Media Player updates. "
