In that case, my advice to you, is to try running windows refresh,
Point to the upper-right corner of the screen, move the mouse pointer down, click Settings, and then click Change PC settings.
Click Update and recovery, and then click Recovery.
Under Refresh your PC without affecting your files, click Get started.
Follow the instructions on the screen.
Apps you installed from websites and DVDs will be removed. Apps that came with your PC and apps you installed from the Windows Store will be reinstalled. Windows puts a list of removed apps on your desktop after refreshing your PC.
