Зачем откатываться, если можно удалить так:

Start >> All Programs >> Microsoft Office >> Microsoft Office 2010 Tools >> Microsoft Office 2010 Language Preferences

Or:

Start >> Control Panel >> Change keyboards or other input methods >> Change Keyboards...

Or

Start >> Control Panel >> Region and Language >> Keyboards and Languages >> Change Keyboards...

Or

Start - Control Panel > Regional and Language Option > Languages Tab > Details... > remove it in the "installed services".
