In Microsoft System Center Configuration Manager 2007, you reset the software inventory cache by connecting to the inventory agent namespace and deleting the inventory action status instance for software inventory.

To reset the software inventory cache

Connect to the inventory agent namespace (root\ccm\invagt).
Delete the inventory action status instance for software inventory ({00000000-0000-0000-0000-000000000002}).

Example

The following example method shows how to reset the software inventory cache by connecting to the inventory agent namespace and deleting the inventory action status instance for software inventory.

Sub ResetSoftwareInventoryCache()

    ' Get a connection to the "root\ccm\invagt" namespace.
    Dim locator
    Set locator = CreateObject("WbemScripting.SWbemLocator")
    Dim services
    Set services = locator.ConnectServer( , "root\ccm\invagt")
      
    ' Delete the specified InventoryActionStatus instance.
    services.Delete "InventoryActionStatus.InventoryActionID='{00000000-0000-0000-0000-000000000002}'"      

    ' Display message.
    wscript.echo "Reset Software Inventory cache."
    
End Sub

public void ResetSoftwareInventoryCache()
{
    try
    {
        // Define the scope (namespace).
        ManagementScope inventoryAgentScope = new ManagementScope(@"root\ccm\invagt");
        
        // Load the class that you want to work with.
        ManagementClass inventoryClass = new ManagementClass(inventoryAgentScope.Path.Path, "InventoryActionStatus", null);

        // Query the class for the InventoryActionID object (create query, create searcher object, execute query).
        ObjectQuery query = new ObjectQuery("SELECT * FROM InventoryActionStatus WHERE InventoryActionID = '{00000000-0000-0000-0000-000000000002}'");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(inventoryAgentScope, query);
        ManagementObjectCollection queryResults = searcher.Get();
                        
        // Enumerate the collection to get to the result (there should only be one item returned from the query).
        foreach (ManagementObject result in queryResults)
        {
            // Display message and delete the object.
            Console.WriteLine("Resetting Software Inventory cache.");
            result.Delete();
        }
    }

    catch (System.Management.ManagementException ex)
    {
        Console.WriteLine("Failed to run action. Error: " + ex.Message);
        throw;
    }
}
