What is causing "WINDOWS Explorer" to shutdown my laptop with Message "Windows Explorer has stopped working"

Hello,

IE could have been crashed, I would suggest you to uninstall it completely and install it back.

As of now I dont the version of IE you are using and version of OS.

Thinking it could be IE 11 with win 8 as its latest and steps are below :

Turn off Internet Explorer Because Internet Explorer is a Windows feature, you can't uninstall it, but you can turn it off. Here's how:

1. Swipe in from the right edge of the screen, and then tap Search.
   (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
2. Enter Windows features in the search box, tap or click Settings, and then tap or click Turn Windows features on or off.
3. In the Windows Features dialog box, clear the Internet Explorer 11 check box.

Boot in SAFE Mode
