vb.net and sending remote commands

I am using the below code to run an SCCM update which works fine and i can see it in the logs, when i change the command to run to "taskmgr.exe" or "regedit.exe", it works locally but when attempting to send to a remote workstation, it creates the process but never loads the GUI window.

 

Dim RC As String = TextBox1.Text
        Dim str As String
        'Dim str2 As String
        Try
            Dim theScope As New ManagementScope("\\" & RC & "\root\cimv2")
            Dim objectQuery As New ObjectQuery("SELECT * FROM Win32_OperatingSystem")
            Dim managementObjectSearcher As New ManagementObjectSearcher(theScope, objectQuery)
            Dim managementPath As New ManagementPath("Win32_Process")
            Dim managementClass As New ManagementClass(theScope, managementPath, Nothing)
            Dim managementClass1 As New ManagementClass("Win32_ProcessStartup")
            managementClass1("CreateFlags") = 16777216
            Dim methodParameters As ManagementBaseObject = managementClass.GetMethodParameters("Create")
            Dim text As String = "Trigger SCCM Check"
            If text = "Update Group Policy" Then
                str = "gpupdate /force"
            ElseIf text <> "Trigger SCCM Check" Then
                MessageBox.Show("Please select an option from the list.")
                Return
            Else
                str = "regedit.exe"
                'str = "WMIC /namespace:\\root\ccm path sms_client CALL TriggerSchedule ""{00000000-0000-0000-0000-000000000021}"" /NOINTERACTIVE"
                'str = "WMIC /namespace:\\root\ccm path sms_client CALL TriggerSchedule ""{00000000-0000-0000-0000-000000000026}"" /NOINTERACTIVE"
            End If
            methodParameters("CommandLine") = str
            methodParameters("ProcessStartupInformation") = managementClass1
            Dim managementBaseObject As ManagementBaseObject = managementClass.InvokeMethod("Create", methodParameters, Nothing)
            Dim str1 As String = managementBaseObject("ReturnValue").ToString()
            String.Concat("ReturnValue: ", str1)
        Catch exception As Exception
            MessageBox.Show("The command failed to execute.")
        End Try
