Windows 7 Professional, Service Pack 1
Intel Core i5 2.8GHz 4 Cores
When I launch Windows Explorer using the mouse click the Windows Start button then "Documents", Windows Explorer launches immediately.
But, when I launch Windows Explorer using the keyboard shortcut Win-E it takes 20-30 seconds to load.
It used to be fast, so something has changed to make it slow.
How can I find identify the cause and fix it?
