使用WMI和檢查服務包的一部分進行彙總包Win32_QuickFixEngineering枚舉。

從的TechNet：

strComputer = "." 
Set objWMIService = GetObject("winmgmts:" _ 
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") 
Set colQuickFixes = objWMIService.ExecQuery _ 
    ("Select * from Win32_QuickFixEngineering") 
For Each objQuickFix in colQuickFixes 
    Wscript.Echo "Computer: " & objQuickFix.CSName 
    Wscript.Echo "Description: " & objQuickFix.Description 
    Wscript.Echo "Hot Fix ID: " & objQuickFix.HotFixID 
    Wscript.Echo "Installation Date: " & objQuickFix.InstallDate 
    Wscript.Echo "Installed By: " & objQuickFix.InstalledBy 
Next 

的HotFixID是要檢查什麼。

這裏是我的系統上的輸出：

最可靠的方法是確定哪些文件受到QFE的影響，並在每個文件上使用System.Diagnostics.FileVersionInfo.GetVersionInfo(path)並比較版本號。

編輯：我覺得有一種方法來檢查註冊表中的卸載信息爲好，但如果QFE真的成爲可能報告漏報
