WIndow update error will not work - error message 80070422

[Clifford]

Hello, I have a Compaq Presario C500 Laptop with Vista Home edition installed (Intel Celeron M CPU 1.86 GHz/1.50 GB Ram/Vista SP 2.  I've had my Windows update set to automatically download and install any updates.  However I've recently had this error message occur that states "Errors found - Code 80070422.  Windows update encountered an unknown error."  I've tried the "Get Help With This Error" link but it's very confusing.  I've also run my antivirus (microsoft security essentials)/Superantispyware/Malwarebytes to make sure I don't have any virus' and haven't found anything.  Can somebody help me?  Thanks.
P.S.  User Mulreay said I should repost in this area.
