This is similar to the problem I have 50 oem machines with label keys on top so I created a script to read the serial number from the bios and change the key and activate.

[CODE]’ Use “wmic bios get serialnumber” to get the serial number if its not documented elsewhere.
Dim sSerial
Dim sKey
set cnn = createobject(“adodb.connection”)
set rs = createobject(“adodb.recordset”)
Set objWMIService = GetObject(“winmgmts:” _
& “{impersonationLevel=impersonate}!\.\root\cimv2”)
Set colBIOS = objWMIService.ExecQuery _
(“Select * from Win32_BIOS”)
For each objBIOS in colBIOS
sSerial = objBIOS.SerialNumber
Next
cnn.open “Provider=Microsoft.Jet.OLEDB.4.0; Data Source=.; Extended Properties=”“text;HDR=Yes;”“”
rs.open “select * from serials.csv where Serial='” & sSerial & “'”, cnn, 3, 3

Do until rs.eof
sKey = rs.fields.item(“key”).value
rs.MoveNext
loop
If Not IsEmpty(sKey) Then
Dim objShell
Set objShell = Wscript.CreateObject(“WScript.Shell”)
objShell.Run "c:\windows\system32\cscript c:\windows\system32\slmgr.vbs /ipk " & sKey,1,TRUE
objShell.Run “c:\windows\system32\cscript c:\windows\system32\slmgr.vbs /ato”,1,TRUE
Set objShell = Nothing
End If

[/CODE]

This reads a csv file called serials so its easy to update.

[CODE]Serial,Key
HKCF91LC102731,abcde-fghij-klmno-pqrst-uvwxy
[/CODE]

I call this from the setupcomplete.cmd as outlined in the main windows 7 fog guide so everything is activated with the correct key right from the word go
