Wusa.exe c:\temp\FILExxxxx.msu /quiet /norestart
Otherwise you can use following script that will parse all the files in the same directory as the script and install all files which ends with .MSU automatically.
Dim objfso, objShell
Dim folder, files, sFolder, folderidx, Iretval, return
Set objfso = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("Wscript.Shell")
sFolder = left(WScript.ScriptFullName,
(Len(WScript.ScriptFullName))-(len(WScript.ScriptName)))
Set folder = objfso.GetFolder(sFolder)
Set files = folder.Files
For each folderIdx In files
If Ucase(Right(folderIdx.name,3)) = "MSU" then
wscript.echo "wusa.exe " & sfolder & folderidx.name & " /quiet /norestart"
iretval=objShell.Run ("wusa.exe " & sfolder & folderidx.name & " /quiet /norestart", 1, True)
If (iRetVal = 0) or (iRetVal = 3010) then
wscript.echo folderidx.name & " Success"
Else
wscript.echo folderidx.name & " Failed"
wscript.quit(1)
End If
End If
Next
