I no longer need to support a language pack on my MOSS SP3, Aug 12 CU server. I have tried to remove it from Control Panel but it is unable to uninstall the Hotfix for WSS (KB2687331). How can I remove it?
KB2687331 is a SharePoint cumulative hotfix. Cumulative hotfixes and service packs in SharePoint cannot be uninstalled once deployed. This is because every update makes changes to the database schema which cannot be undone.
The language packs themselves should be able to be uninstalled from the control panel however. A cumulative hotfix however contains all available languages (service packs don't).
