I'm sorry for the inconvenience. Can you please right click on your menu bar, select "Customize", then select "Menu Bar" from the list of toolbars and then click the "Reset" button.
If this doesn't help you could try install JustCode and the uninstall it again.
Once again I'm sorry for the inconvenience. We use the VS automation to remove the registered commands on uninstall but unfortunately sometimes VS fails to do it (either it's busy or something else).
All the best,
the Telerik team
