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.
