error 80070490 trying to do the update of windows Vista. How to solve

I'm urged repeatedly to allow an update of windows.  I'm sure that I need, but it is no help ANYWHERE on the web for 80070490 'unknown error' this error prevents any update and is a problem.

There are dozens of other error codes answers, but none that apply to this error.  I'm just the update proposed by windows on a laptop with Vista that has no other significant attachment problems.

There must be an error code and "how to fix" somewhere.  At least, it seems to reduce the demand for technical assistance from IS.

Thank you
