I’ll show you how to determine within the Configuration Manager console what software updates (SUs) are missing and how to make a Software Update Group for them.
Many years ago, I published a blog post to help folks track down issues involving Hardware Inventory. By accident, while helping someone troubleshoot ConfigMgr hardware inventory issues, I noticed that a step was missing. In 99% of cases, no one would need or notice this step, but since I realized it was missing I decided to update my post.
From now on this guide should help pinpoint any (I hope) issues within the inventory flow from PC to Configuration Manager (ConfigMgr) database.
