Microsoft Office reserves the value of {00000000-0000-0000-0000-000000000000} for its default signature provider, and {000CD6A4-0000-0000-C000-000000000046} for its East Asian signature provider. The GUID of the additionally installed provider should be obtained from the documentation shipped with the provider.
