Windows Update via VBS

Put together something that will enable you to perform Windows Update by means of the vbs.
In this vbs, I have decided that I do not want to include any updates for Dot Net Framework and Windows Search.

'ServerSelection values
ssDefault = 0
ssManagedServer   = 1
ssWindowsUpdate   = 2
ssOthers          = 3

'InStr values
intSearchStartChar = 1

dim strTitle

Set updateSession = CreateObject("Microsoft.Update.Session")
Set updateSearcher = updateSession.CreateupdateSearcher()

updateSearcher.ServerSelection = ssWindowsUpdate
Set searchResult = updateSearcher.Search("IsInstalled=0 and Type='Software'")

WScript.Echo "List of applicable items on the machine:"

For I = 0 To searchResult.Updates.Count-1
    Set update = searchResult.Updates.Item(I)
    WScript.Echo I + 1 & "> " & update.Title
Next

If searchResult.Updates.Count = 0 Then
    WScript.Echo "There are no applicable updates."
    WScript.Quit
End If

WScript.Echo vbCRLF & "Creating collection of updates to download:"

Set updatesToDownload = CreateObject("Microsoft.Update.UpdateColl")

For I = 0 to searchResult.Updates.Count-1
    Set update = searchResult.Updates.Item(I)
    addThisUpdate = false
if instr(lcase(update.title),".net framework") = 0 then  
if instr(lcase(update.title),"search") = 0 then  
If update.InstallationBehavior.CanRequestUserInput = true Then
        WScript.Echo I + 1 & "> skipping: " & update.Title & _
        " because it requires user input"
    Else
        If update.EulaAccepted = false Then
            WScript.Echo I + 1 & "> note: " & update.Title & _
            " has a license agreement that must be accepted:"
            WScript.Echo update.EulaText
            WScript.Echo "Do you accept this license agreement? (Y/N)"

            strInput = "Y"
            WScript.Echo
            If (strInput = "Y" or strInput = "y") Then

                addThisUpdate = true
            Else

        updatesToDownload.Add(update)
    End If
Next

If updatesToDownload.Count = 0 Then
    WScript.Echo "All applicable updates were skipped."
    WScript.Quit
End If
   
WScript.Echo vbCRLF & "Downloading updates..."

Set downloader = updateSession.CreateUpdateDownloader()

downloader.Updates = updatesToDownload
 Set downloadResult = downloader.Download()
   WScript.Echo "Download Result: " & downloadResult.ResultCode
'downloader.Download()

Set updatesToInstall = CreateObject("Microsoft.Update.UpdateColl")

rebootMayBeRequired = false

WScript.Echo vbCRLF & "Successfully downloaded updates:"

For I = 0 To searchResult.Updates.Count-1
    set update = searchResult.Updates.Item(I)
    If update.IsDownloaded = true Then
        WScript.Echo I + 1 & "> " & update.Title
        updatesToInstall.Add(update)  
        If update.InstallationBehavior.RebootBehavior > 0 Then
            rebootMayBeRequired = true
        End If
    End If

    WScript.Quit
End If
