(VB.NET) Is there a way to do a check for a Windows Security Update in Win7?-CodePudding

I want to check for a specific Windows Security Update in my WinForm running on an offline standalone Win7 Kiosk Machine. I think I have an infinite loop cause it just hangs when I run this code. I can't seem to find my issue. I found similar code in C# and tried to convert it to VB.NET but maybe I didn't do it correctly.

I basically just want to check the system for KB3033929 and then if it is installed, hide a button and show a label.

' ***** CHECK FOR PATCH *****
Dim objSession = CreateObject("Microsoft.Update.Session")
Dim objSearcher = objSession.CreateUpdateSearcher
Dim objResults = objSearcher.Search("Type='Software'")
Dim colUpdates = objResults.Updates
For i = 0 To colUpdates.Count - 1
    If colUpdates.Item(i).Title = "Security Update for Windows (KB3033929)" Then
        If colUpdates.Item(i).IsInstalled <> 0 Then
            Label4.Visible = True
            PatchInstall.Visible = False
        End If
    End If
Next

Please correct me if I am wrong, but after more research I think this does what I need? I honestly am still trying to understand it, but after installing the patch I get the popup from the MsgBox with this code:

'***** CHECK FOR PATCH *****
Private Sub CheckPatch()
    Dim ConOptions As New ConnectionOptions() With {.EnablePrivileges = True, .Timeout = EnumerationOptions.InfiniteTimeout}
    Dim mOptions As New EnumerationOptions() With {.Rewindable = False, .ReturnImmediately = True, .DirectRead = True, .EnumerateDeep = False}
    Dim mQuery As New SelectQuery("SELECT HotFixID FROM Win32_QuickFixEngineering WHERE HotFixID = 'KB3033929'")
    Dim mScope As New ManagementScope($"\\{Environment.MachineName}\root\CIMV2", ConOptions)
    mScope.Connect()
    Using moSearcher As New ManagementObjectSearcher(mScope, mQuery, mOptions)
        If moSearcher.Get().Count > 0 Then
            MsgBox("Patch Installed!")
        End If
    End Using
End Sub
