Get update information from windows server of WyBuild

We met a small problem recently that we failed to get update information if we set WyBuild process as a windows server. I went through the help documentation for wyUpdate commandline and found the return code is such as 1,2

More information is needed:

1. What are you trying to do?

2. What are you doing?

3. What results did you get?

4. What results did you expect?

Code of what you're doing is useful when applicable.
