If my memory serves me correctly
Open the Start Menu
Right-click on 'Control Panel' and click 'Show on Desktop'
Right-click on the 'Control Panel' icon and click 'Create Shortcut'
Right-click on the 'Control Panel - Shortcut' icon and click 'Properties'
Under the 'Shortcut' tab, set the 'Shortcut key' field and press the desired key combination e.g. Ctrl+Alt+C (if you want a shortcut key)
soz I'm not at my Win 7 rig at the moment so I can't test it
