Patch Assessment queries performed using the 'Patch Assessment' and 'WSUS Patch Assessment' data sources returning different results using bv-Control for Windows
This is due to the underlying architecture of each data source. The Patch Assessment data source relies on its own list of patches from all vendors. In contrast, the WSUS Patch Assessment data source uses a list of patches created by Microsoft alone, and obtains the list from the update source configured on the target computer. If the target connects to a WSUS server to obtain patches, then only patches that are "Approved for Install" on the WSUS Server will be included in the assessment. If the target computer is subscribed to either the Microsoft or Windows Update Service, then all patches published on the Update Server will be included.
To be specific, we do not query or search for any WSUS server present in the organization while collecting the patch assessment information. However, when any query comes for the WSUS patch assessment against any machine, RMS will first check if the WUS Client is installed on the machine or not. If client exist, then depending on WSUS patch assessment source options: “WSUS Server” or” Windows update site” we set the source for the WSUS client. Then we query for the patch information from the client, the client itself contacts to the registered WSUS server in its organization, and it returns the required information.
If a WSUS server is not installed, by default, all machines point to windows update site. So for patch assessment query select “windows update site” and you can view patch results. You can run a query on “WSUS Server” and scope to a particular machine to figure out to which WSUS server that machine is registered with.
Note: Query Engine need to be present on the WSUS Server – if you are reporting on Window servers.
