The EnumerateUpdates method, in Configuration Manager, determines actionable software updates that are available for the client computer.

HRESULT EnumerateUpdates(
     const ULONG ulUpdateAction,
     const VARIANT_BOOL bIncludeHidden,
     VARIANT* pvarProgress,
     LPICCMUpdatesCollection* ppiUpdatesCollection


  • ulUpdateAction
    Data type: ULONG

    Qualifiers: [in]

    Update action. Possible values are:


    UPDATE_ACTION_INSTALL. This setting retrieves all updates that are available to be installed or in the process of being installed.


    UPDATE_ACTION_UNINSTALL. This setting retrieves updates that are already installed and are available to be uninstalled.


    Uninstall of updates through this interface is not currently supported.

  • bIncludeHidden
    Data type: VARIANT_BOOL

    Qualifiers: [in]

    VARIANT_FALSE to retrieve only the updates that are available through the client user interface.


    In quiet mode, set this parameter to VARIANT_TRUE to retrieve the updates through this method.

  • pvarProgress
    Data type: VARIANT

    Qualifiers: [in, out]

    Pointer to an unsigned long value within a variant indicating if any job is currently active. Possible values are:







  • ppiUpdatesCollection
    Data type: LPICCMUpdatesCollection

    Qualifiers: [out, retval]

    Pointer to an ICCMUpdatesCollection Interface object representing the collection of software updates for deployment.

Return Values

An HRESULT code. Possible values include, but are not limited to, the following:

  • S_OK
    The method succeeded.


The caller uses the EnumerateUpdates method on a CCMUpdatesDeployment COM Automation Class object to determine what actionable updates are available for the client computer. These updates can then be displayed in the main updates portion of the Configuration Manager console or in another client application-specific way. For implementation instructions, see How to Enumerate Software Updates.

The caller is responsible for releasing the updates collection retrieved in the ppiUpdatesCollection parameter.
