1660  * HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
1661  * or in the same location in HKLM.
1662  * The registry usage is explained by the following tech note:
1663  * http://www.microsoft.com/windows2000/techinfo/reskit/en-us/default.asp?url=/windows2000/techinfo/reskit/en-us/regentry/36173.asp
1664  * The "Shell Folders" registry key was used in NT4 and earlier systems.
1665  * Beginning with Windows 2000, the "User Shell Folders" key is used, so
1666  * changes made to it are made to the former key too.  This synchronization is
1667  * done on-demand: not until someone requests the value of one of these paths
1668  * (by calling one of the SHGet functions) is the value synchronized.
1669  * Furthermore, as explained here:
1670  * http://www.microsoft.com/windows2000/techinfo/reskit/en-us/default.asp?url=/windows2000/techinfo/reskit/en-us/regentry/36276.asp
1671  * the HKCU paths take precedence over the HKLM paths.
