If I want to open or save a file using a program in Windows Vista or higher, the location which is opened by default usually¹ is the "Documents" library. How can I change this default location system-wide?
¹ Most applications behave like this when opening/saving a file for the first time.

Also note that application also have the power to open up the save dialog to a custom folder. Many just let the OS handle it, though.
