If you mean the Support Assist desktop icon which (probably) went away when an updated version of SA was installed on your system then the following steps should work.

      1.  Bring up the program list by either pressing the Windows key or clicking the Windows icon in the lower left corner of the screen.

       2.  In the program list find the small icon for "Support Assist".  There may be one near the top of the list in the "Recently added" program section.  If there is not one there then look in the "S" section for "Support Assist".  Right click on the icon or the program name.

       3.  Select the "Pin to Start" option by clicking on it.

       4.  Find the newly added  "Support Assist" icon in the Start Menu.  Left click on that icon and, while holding down the left mouse button, drag the icon to a convenient open space on the desktop.  Release the mouse button and you will have created a "Support Assist" link / shortcut on the desktop.  (The "Support Assist" icon in the Start Menu will still be in the Start Menu.  You can either "unpin" it or keep it there for future use, as you choose.)

       5.  The next time Support Assist is updated or reinstalled the desktop icon will probably disappear and sometimes the one in the Start Menu will go also, but it's easy enough to recreate.
