Open Patches › updates. Set the status filter to everything so approved rows stay in the list. Every source is both inventories. The September cumulative update is Windows Update, important, already approved, and it wants a restart. Google Chrome is winget, moderate, and still awaiting. The count is 2 of 2. Search matches the title, the KB, or the id. Hide Defender definitions is the checkbox beside the menu. Example Co has no definition update, so ticking it leaves both rows.
Set the source menu to Windows Update. Chrome drops out. The cumulative update stays, and the count is 1 of 2. winget is the other item in this company's menu. Set the menu back to every source to see both again. This filter does not approve or install anything.
