I am working on a computer that has Windows 10 installed. The taskbar is missing Microsoft edge and the icon for the windows store. Also the start button only works if you do a right click and then choose an option in black and white. The start menu I had when I first installed windows 10 does not come up when I do a left click on the windows flag...the start button. What might have caused this and how to I solve this problem? The icons on the desktop all work...and I have set chrome as my default browser as a result of this problem. Do you think it might be as a result of a windows update that has gone awry? If not what has happened?
