Problem: File Explorer in Windows 10 fails to open and just flicks for a second and does nothing.

Question: Did you or a family member change the size of the text or font recently? If the answer is Yes then this is most likely the cause of the problem.

Solution: 

  1. In the Search bar at the bottom of the screen type “Change the size” and then at the top of the search results menu, click on the link that appears.
    Change the size
  2. Look for the ‘Change the size of text, apps, and other items‘ slider and change it to 150% if it is set to something higher.
    Change to 150%
  3.  Your File Explorer or Control Panel will now open.
