PowerShell cannot find some Verbs of executable

I'm new to PowerShell. Now the task is to pin some programs to the Taskbar. This Tutorial is great and runs well in one of my Win7 32bit in Vmware. But same script cannot run in Win10 32bit in Vmware. So I modified the code and finally found it was because some Verbs are not found. My test code is as following:

CLS
$cmd = 'C:\Windows\System32\cmd.exe'
Test-Path $cmd
$Shell = New-Object -ComObject Shell.Application
$Desktop = $Shell.NameSpace(0X0)
$itemLnk = $Desktop.ParseName($cmd)
$itemVerbs = $itemLnk.Verbs()
Foreach($v in $itemVerbs)
{
    write-host $v.Name
}

The ISE is run as admin and the result, as well as 'Verbs' found by mannually right clicking the cmd.exe, are shown as below:

So please tell me why and how to fix this, thank you!

Its probably because there is no cmd.exe located in C:\Windows\, use this instead:

$cmd = Join-Path $env:SystemRoot 'System32\cmd.exe'

Note: Im using the Join-Path cmdlet to combine the path and $env:SystemRoot to retrieve the system root (e. g. C:\Windows)

You can only use verbs above the first separator and Properties. Your program must keep running to display properties.

Here's a VBScript that list and performs the verb. ShVerb.vbs /? to read the above.

HelpMsg = vbcrlf & "  ShVerb" & vbcrlf & vbcrlf & "  2014" & vbcrlf & vbcrlf & "  Lists or runs an explorer verb (right click menu) on a file or folder" & vbcrlf  & vbcrlf & "    ShVerb <filename> [verb]" & vbcrlf & vbcrlf & "  Used without a verb it lists the verbs available for the file or folder" & vbcrlf & vbcrlf
HelpMsg = HelpMsg & "  The program lists most verbs but only ones above the first separator" & vbcrlf & "  of the menu work when used this way" & vbcrlf & vbcrlf 
HelpMsg = HelpMsg & "  The Properties verb can be used. However the program has to keep running" & vbcrlf & "  to hold the properties dialog open. It keeps running by displaying" & vbcrlf & "  a message box." 
Set objShell = CreateObject("Shell.Application")
Set Ag = WScript.Arguments 
set WshShell = WScript.CreateObject("WScript.Shell") 
Set fso = CreateObject("Scripting.FileSystemObject")

    If Ag.count = 0 then 
        wscript.echo "  ShVerb - No file specified"
        wscript.echo HelpMsg 
        wscript.quit
    Else If Ag.count = 1 then 
        If LCase(Replace(Ag(0),"-", "/")) = "/h" or Replace(Ag(0),"-", "/") = "/?" then 
            wscript.echo HelpMsg 
            wscript.quit
        End If
    ElseIf Ag.count > 2 then 
        wscript.echo vbcrlf & "  ShVerb - To many parameters" & vbcrlf & "  Use quotes around filenames and verbs containing spaces"  & vbcrlf
        wscript.echo HelpMsg 
        wscript.quit
    End If

    If fso.DriveExists(Ag(0)) = True then
        Set objFolder = objShell.Namespace(fso.GetFileName(Ag(0)))
'       Set objFolderItem = objFolder.ParseName(fso.GetFileName(Ag(0)))
        Set objFolderItem = objFolder.self
        msgbox ag(0)

    Else
        wscript.echo "  ShVerb - " & Ag(0) & " not found"
        wscript.echo HelpMsg 
        wscript.quit
    End If

    Set objVerbs = objFolderItem.Verbs

    'If only one argument list verbs for that item

    If Ag.count = 1 then
        For Each cmd in objFolderItem.Verbs
            If len(cmd) <> 0 then CmdList = CmdList & vbcrlf & replace(cmd.name, "&", "") 
        Next
        wscript.echo mid(CmdList, 2)

    'If two arguments do verbs for that item

    ElseIf Ag.count = 2 then
        For Each cmd in objFolderItem.Verbs
            If lcase(replace(cmd, "&", "")) = LCase(Ag(1)) then 
                wscript.echo(Cmd.doit)
                Exit For
            End If
        Next
    'Properties is special cased. Script has to stay running for Properties dialog to show.
        If Lcase(Ag(1)) = "properties" then
            WSHShell.AppActivate(ObjFolderItem.Name & " Properties")
            msgbox "This message box has to stay open to keep the " & ObjFolderItem.Name & " Properties dialog open."
        End If  
    End If
End If
