Hello Brian, and welcome to Seven Forums.
In addition to what Noel posted to help make sure that your system is clean, double check to make sure that you have the services in bold below set to
Started and
Automatic (Delated Start). If they are not listed in your Services window, then you could use the tutorial below to restore them.
Services - Restore Default Services in Windows 7- Windows Update
- Background Intelligent Transfer Service
After they are restored, use OPTION TWO in the tutorial below to reset and re-register Windows Update, then see if your Windows Update will work now.
Windows Update - Reset
Hope this helps,
Shawn
