I happened to have deleted the Show Desktop icon in my quicklaunch bar the other day. Now I didn't realize how much I used this lovely little button until it was gone. So I search with the mighty google and found the following:
It is fairly easy to restore the "Show Desktop" button that usually resides in the Quick Launch toolbar, if you have removed it.
Open notepad and paste the following:
[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop
Save the file as "Show Desktop.scf" in C:\Documents and Settings\<YOURNAME>\Application Data\Microsoft\Internet Explorer\Quick Launch where YOURNAME is the username of the account that is missing the icon.

Now I'm wondering, what are these .scf files and where are they documented? More importantly what else do they do?
