// A: Not a whole lot.
// We used to store a variant in the registry. Unfortunately, variants are
// 16 bytes on Win32 (8 byte header + 8 bytes of data)
// 24 bytes on Win64 (8 byte header + 16 bytes of data)
// Unfortunately, Win64 webcheck and Win32 webcheck both read from
// the same registry location, i.e. the same blob, and won't understand one another.
// Thus, boom! At least, for BSTRs that are stored inline
// Fortunately, we care only about only the first 16 bytes on both platforms.
// Ergo, it's sufficient to store only the top half of the Win64 variant.
