Here’s how:

  1. Open Quick Access in a new window
  2. Select All
  3. Copy
  4. Go to an empty folder
  5. Paste shortcut
  6. Your Quick Access items are now ‘normal’ shortcuts

You can quickly clear the auto-populated entries from Quick Access by using Clear File Explorer history after right-clicking on Quick Access and going to Options:

Finally, you can multi-select File Folders in Quick Access and Unpin them all at once from the right-click menu.

After upgrading to Windows 10, I decided to clear out my Quick Access using above steps, and then incrementally add items back by using the shortcut backup that I created.
