I am working on learning new dashboards along side figuring out SWQL queries. I followed along in the lab and created this dashboard to for the basics of dashboards.

I am doing some small changes to the SWQL queries so this page only shows Windows nodes. Which was easy -

I would like to have the rest of the widgets on the page only grabbing data from nodes that are Windows and that is where I am having an issue. Can someone point me in the direction of how to sort these so it is they are just Windows Devices? I think I may need to do a JOIN clause but not entirely sure. I was reading another THWACK article that described how to use custom properties to filter by but I think I am missing something.
SELECT COUNT(1) AS Count_Items, Status
FROM ORION.Nodes
JOIN Orion.NodesCustomProperties ON nodes.nodeid = NodesCustomProperties.nodeid
WHERE Business_Region = 'EMEA'
AND
Client = 'Client A'
GROUP BY Status
Thanks and there will be probably more questions coming. Thanks - Dave
