Cea mai simpla solutie este un script VBS care schimba modul de start a serviciului dupa care restarteaza calculatorul (stiu, e o solutie care consuma timpul):

 'Dezactivare/activare cdrom
computer     = "."    
serviciu    = "cdrom"        
modstart    = "Disabled"    ' Disabled=dezactivare sau Automatic=activare    

Set oInstance     = GetObject("winmgmts:{impersonationLevel=impersonate}//" & computer & _
    "/root/cimv2:Win32_Service=" & Chr(34) & serviciu & Chr(34))

rez         = oInstance.ChangeStartMode(modstart)
text        = "OK"
If rez <> 0 Then text = "esec"
WScript.Echo "Rezultat ChangeStartMode: " & text

WScript.Echo "URMEAZA RESTART !"

'Restart
forteazarestart    = 6
Set oOS = GetObject("winmgmts:{(Shutdown)}").ExecQuery("Select * from Win32_OperatingSystem")
For Each oOperatingSystem in oOS
    oOperatingSystem.Win32Shutdown(forteazarestart)
Next
