Why won't my start menu open?

[Windows Central Question]

After installing the Windows 10 upgrade onto my laptop I am no longer able to get the start menu to open either by clicking the windows symbol or using the windows key on the keyboard.

What about Cortana(search function) does it work?
Your taskbar might be broken, try restarting your device
