Dim strComputer, objWMIService, colQuickFixes, objQuickFix, HFInstalled, HFID
strComputer = "."
HFID = "KB958830"
HFInstalled = False
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colQuickFixes = objWMIService.ExecQuery ("Select * from Win32_QuickFixEngineering")
For Each objQuickFix in colQuickFixes
  If objQuickFix.HotFixID = HFID Then
      HFInstalled = True
      Exit For

Next
