Purpose of this article
If SCCM is properly installed on the endpoint device and shows up properly in the management console, but is not pulling applications/settings in line with its collections, try these steps to have it manually check in.
Steps
Open your Control Panel and click the Configuration Manager button. You may need to change your view option to Small icons or Large icons for it to appear more visibly in the list.

In the window that opens, click the Actions tab near the top. You should see a list of actions to run similar to the screenshot below. If your list is shorter, most often containing only 2 or fewer items, it is likely that your SCCM client is not properly installed on your device and needs to be uninstalled and reinstalled from scratch.

Click on an item and then click the Run Now button at the bottom. Repeat this for each item, dismissing the confirmation dialogue box that pops up for each one. After a few minutes, your endpoint client should sync up with the management console and start displaying applications/settings correctly.
