You lost the shortcut?? First you need to know the target for the shortcut. In
your case it is %systemroot%\system32\cleanmgr.exe. Once you know that, you
can right click on the desktop select new--shortcut and follow the prompts.
That will put the shortcut on your desktop. Then all you have to do is drag it
to the system tools folder.After its in the tools folder you can right click
the desktop and delete it from there.
