Your registry command removes the entire Language Bar CLSID tree, so you'll probably need to re-import it. FWIW, here's mine: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\CLSID\{540D8A8B-1C3F-4E32-8132-530F6A502090}] @="Language bar" "MenuTextPUI"="@%SystemRoot%\\System32\\msutb.dll,-325" [HKEY_CLASSES_ROOT\CLSID\{540D8A8B-1C3F-4E32-8132-530F6A502090}\Implemented Categories] [HKEY_CLASSES_ROOT\CLSID\{540D8A8B-1C3F-4E32-8132-530F6A502090}\Implemented Categories\{00021492-0000-0000-C000-000000000046}] [HKEY_CLASSES_ROOT\CLSID\{540D8A8B-1C3F-4E32-8132-530F6A502090}\InProcServer32] @="C:\\WINDOWS\\system32\\msutb.dll" "ThreadingModel"="Apartment"
