As Pegasus said, you're in the wrong group
unless you want to do it via script. If so,
you need WMI.

Here's some "air code" to do it. I can't vouch for
total accuracy, as it's still early in the morning
for me and I just pulled this code out a larger script:

sStartName = "wuauserv"

Set WMI = GetObject("WinMgmts:")
Set oServ2 = WMI.Get("Win32_Service.Name='" & sStartName & "'")
iRet = oServ2.ChangeStartMode("disabled")
If (oServ2.State = "Running") Then iRet2 = oServ2.StopService
Set oServ2 = Nothing
Set WMI = Nothing

The "XPFix" download there includes an HTA GUI program
for cleaning up unnecessary services. The file XPFixOpsS.vbs,
in the download, is where the code is for checking, starting,
stopping and changing services status. Note, though, that
WMI is not foolproof. I've found that some services set to
disabled somehow get started again, even though they may
not be necessary services. I haven't taken the trouble to
research exactly which services are problematic that way,
but I think it's a good idea to keep an eye on services that
you *think* are under your control.
