Windows update error code 80246008
BITS service failed to start. Error 0x80070422

The background intelligent transfer service is set to automatic start, but
will not start. Attempting to start the service from services.msc results in:

"Windows could not start the Background Intelligent Transfer Service on Local
Computer. For more information, review the System Event Log. If this is a
non-Microsoft service, contact the service vendor, and refer to
service-specific error code -2147023838."

The reason for this is that the BITS service has an undocumented, unlisted
dependency on the (otherwise useless) Network List Service. Enable and start
that service, then BITS will start.
