The update 80244019 error is:
or Not Found error message
is a HTTP standard response code
indicating that the client
was able to communicate with the server but the server could not find what was requested. 404 errors should not be confused with "server
not found" or similar errors, in which a connection to the destination server could not be made at all.
It says that Windows Update was able to communicate with the Windows Update server - but it could not find what it was looking for.
My first suggestion would be to try again. If that doesn't work, then we'll have to try some of the Windows Update fixes that are floating around the web.
