How to enable 'Classic Update' in Eclipse

Some versions of eclipse do not allow you to remove software using the 'Help > Install New Software' link. You need to go to 'Help > Software Updates > Manage Configuration' however this option is not there....

You can enable this in preferences in 'Window > Preferences' then 'General > Capabilities' but you can be scuppered because this menu is not there under General. In this case, edit your :

WORKSPACE/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.workbench.prefs

and add a line at the end :

UIActivities.org.eclipse.equinox.p2.ui.sdk.classicUpdate=true

You can then get to the Manage Configuration section!
