SCCM Collection Incremental updates not Working because of non Supported WMI Classes ConfigMgr

Let’s understand more about SCCM Collection Incremental updates not Working because of non Supported WMI Classes. There are a set of WMI classes that are not supported with SCCM collection incremental updates. Let’s check what the not supported SCCM collection incremental updates WMI classes are?

Let’s understand what is the best practice while creating collections. You should not enable incremental updates for all the collections in your SCCM (ConfigMgr) hierarchy. A high number of collections with incremental updates can cause performance issues for the entire Configuration Manager infrastructure.

There are tools within the admin console that can help you analyze the evaluation cycle of collections. One of them is explained ConfigMgr Collection Full Incremental Evaluation Status Summary from Console in the post.

SCCM Collection Incremental updates

An incremental update periodically evaluates new resources and then adds resources that qualify to this collection. This option doesn’t require you to schedule a full update for this collection.

There was an option to have incremental updates during my initials days of device management with SMS 2003 and I think with SCCM 2007. The incremental update for collections got introduced in ConfigMgr 2012 onwards. Let me know whether this is accurate information or not in the comments.

Incremental updates of the SCCM collection are handy to reduce the full collection evaluations for many collections. Full evaluation of collection is more costly in terms of performance. However, an incremental update of collections is just a “delta update” of the collection—more details on Microsoft docs.

How to Find WMI Classes from ConfigMgr Server

WMI is Windows Management Instrumentation, a sort of database where information are stored locally on Windows devices. You can use WBEMTEST tool from any Windows devices to find out the WMI classes that are supported by SCCM.

The easiest way is to download WMI Explorer Tool from Vinay Pamnani and browse through the WMI classes and more. I have a more detailed post on Windows 10 WMI Explorer Details for Configuration Manager and Intune.

SCCM Collection Incremental updates not Working

Let’s understand why incremental updates not working because of non Supported WMI Classes used in WQL queries.

The following are the Microsoft documented WMI classes that won’t support incremental updates of the collections. Some WMI classes are only applicable to dynamic user collections.

If you use the following WMI classes inside the WQL query for dynamic collection, then the incremental update of those dynamic collections won’t work as expected.

The following table of WMI classes are not supported to use along with incremental collection updates. These are applicable for generic set of collections.

WMI Classes Not Supported for SCCM Collection Incremental Updates
SMS_G_System_CollectedFile
SMS_G_System_LastSoftwareScan
SMS_G_System_AppClientState
SMS_G_System_DCMDeploymentState
SMS_G_System_DCMDeploymentErrorAssetDetails
SMS_G_System_DCMDeploymentCompliantAssetDetails
SMS_G_System_DCMDeploymentNonCompliantAssetDetails
SMS_G_System_SoftwareUsageData
SMS_G_System_CI_ComplianceState
SMS_G_System_EndpointProtectionStatus
SMS_GH_System_*

The following two WMI classes are not supported for SCCM dynamic user collections.

User Collection – WMI Classes Not Supported for SCCM Collection Incremental Updates
SMS_G_User_DCMDeploymentCompliantAssetDetails (for collections of users only)
SMS_G_User_DCMDeploymentNonCompliantAssetDetails (for collections of users only)
