First off, there are other ways of running the Computer Management
console. The easiest is to right click on My Computer and select Manage
from the menu. Or you could go to Start -> Run and enter compmgmt.msc in
the Open box.
If you want a shortcut in the Administrative Tools folder, do the
following.
Right click on an open spot in the folder and select New -> Shortcut from
the menu.
Copy and paste the following command into the location box.
%SystemRoot%\system32\compmgmt.msc /s
Hit the Next button.
Name your new shortcut Computer Management and hit the Finish button.
Good luck
