VBScript - Deleting an array element

I am trying to write a script that checks for a specific value in the registry and then deletes that value.  In my case, the value is only a subset of the comma separated text within the key value.

I am trying to treat the string "(example: "vmhgfs,RDPNP,LanmanWorkstation,webclient" as an array bySPLITing into multiple elements and then setting the unwanted array element toEMPTY.  I then want to write the value back as a string but without the element I'm removing (Example:"RDPNP,LanmanWorkstation,webclient".

 The script properly reads the value from the registry and the SPLIT function works to separate the elements.  When I try to JOIN the elements into a new string, I still get a ',' (comma) delimiter for the element I've removed (example:,RDPNP,LanmanWorkstation,webclient).  

 How do I do this so that the comma is not created?  Is there a better way to do this?  I know I could parse the text string and remove the comma but that seems like sloppy coding and the element I'm removing is not always in the same place.

Dim strRegArray, strRegValue
Dim I
Set WshShell = CreateObject( "WScript.Shell" ) 'Bind to the Registry provider

strRegValue = WshShell.RegRead( "HKLM\System\CurrentControlSet\Control\NetworkProvider\Order\ProviderOrder" )

strRegArray = Split(strRegValue,",")	'Copy Registry values into an Array 

For I = 0 To UBound (strRegArray)

	If strRegArray(I) = "vmhgfs" Then 
		strRegArray(I) = Empty
	End If
	strNewArray = Join(strRegArray, ",")


Next
	 WScript.Echo strNewArray
