Windows Update has been problematic at times for Win7 (and Vista and 8/8.1) for many months.
This is a solution I found that has worked for me several times and for many others at another forum who had the same issue.
If Windows Update is partially or fully enabled when you try this, you will probably get stuck "checking for updates". WU must be disabled first.
If that process does not work and/or you get error messages with a specific error code, then you probably have a different problem.
