seems to be an issue with MP11 could try rolling back to version 10 then reinstalling 11
or there is a possible reg edit
Control Panel - Icons Missing
Click Start, Run and enter REGEDIT
Go to: HKEY_CURRENT_USER\Control Panel\don't load
Look in the right pane and you'll see the Control Panel Icons that have been disabled. You can either right click on the "don't load" subkey and select Delete to restore all disabled icons, or you can right click on each of the items in the right pane and select Delete to selectively restore them. Scroll up to Control Panel Applets for a listing of what each one is.
The change will be seen the next time you open Control Panel.
