Malcolm Byrne asked me how to configure Windows Explorer to open to a specified folder each time.
You can't configure Windows to do this. But you can create a shortcut that will open Explorer to a particular folder. This is actually a better solution, because you can create multiple such shortcuts to open multiple favorite folders.
From within Explorer, hold down the right mouse button as you drag the folder in question to your desktop or the start menu or wherever you want that shortcut to go. When you let go of the right mouse button, a menu will pop up. Select Create shortcut here.
