Windows 10 File Explorer – unspecified error

I just recently installed the Windows 10 Anniversary edition, by using the Windows Update tool in the settings screen. Ever since, I’ve been getting an error when I try to open File Explorer.

Explorer.exe
“Unspecified error.”

This error happens when I click on the the icon that I’ve pinned to the Task Bar or if I look for it in the Start Menu.

However, if I open up Control Panel and then use the address bar there to switch to File Explorer, it works.
