Sorry is this a request to the best way of displaying the desktop? No background picture, minimum icons (put least-used shorcuts into a folder on the c drive...put link to folder on desktop.
To show desktop immediately above all other opened folders, right click on taskbar (bottom of screen)...select show the desktop.
When I put a picture on my desktop with Picasa I hightlight the picture then go up to `Create` at the top of the page and click on it then click the `Display Picture on Desktop`...simple.
