Unfortunately I do not know exactly what this means. -198 occurs in BatchPatch when the Windows Update Agent (WUA) fails to add the WsusScn2.cab as a scan destination for Windows Update. The HRESULT is the reason code produced by Windows (not by BatchPatch). Under normal circumstances we would only see -198 occur with HRESULT values that indicate the WsusScn2.cab file is missing or corrupt or unsigned.
HRESULT -939523075 converts to C80003FD
However, I cannot find this documented anywhere in Microsoft’s documentation or on the web. We have never seen this error before.
Considering that this appears to be undocumented and that we have never seen nor heard of it before, my best guess is that this is related to your forum posting from yesterday, where it became clear that you are running Windows versions on unsupported hardware. Windows has preventive measures in place to disallow Windows Updates from being performed on OSes running on unsupported hardware, as you know. I think that is the most likely reason you are experiencing the error.
