Windows 7 desktop file storage directory moved to D disk

How can I transfer the desktop file storage directory to the D disk?
The default desktop directory of the computer is in the C disk, how can I transfer the desktop directory to the D disk, preferably Documents and Settings This document is transferred to the D drive.
The things that do this on the system desktop are not lost.
In the normal mode, change the desktop to the d drive, as follows:
First create a folder on the d drive, then click Start --->Run ---> regedit, click HKEY_CURRENT_USER--> Software-->Microsoft-->Windows-->CurrentVersion-->Explorer-->user Shell Folders
Double-click the desktop on the right to pop up a dialog box, and write the data value you want to save to that folder. Path (that is, open the folder, the line in the address bar above), OK, close. The logout system is ok. Later, everything on the desktop is in the d drive.
Documentsand Settings This is not mobile. Many programs or software need to read and write this folder. User temporary files are also read and written in this folder.
