Windows 10: taskbar issues

My son deleted something shortly after installing windows 10,
on his laptop, now he can not left click on anything in the taskbar.
Just has the hourglass thing run for a few seconds and then disappears.
with nothing else happening.

Just wondering how to restore

Thanks in advance

Taskbar issue

No changes made, no error messages, no new applications. I am not able to log into Pandora on Chrome. But I was able to get it working on Microsoft Edge. No troubleshooting done.

 

Taskbar issue

I need help getting my desktop to function the same as it did last week. For some reason, the taskbar isn't functioning the same. For example, last week when I had multiple programs open such as Excel, Outlook, QuickBooks (QB), and Word, I could switch
between them by clicking on the icon for that program in my taskbar at the bottom of the screen. Now when I click on the icon it tries to open a separate instance of the program.
