Answer 1

使用WMI和检查服务包的一部分进行汇总包Win32_QuickFixEngineering枚举。

从的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是要检查什么。

这里是我的系统上的输出：

最可靠的方法是确定哪些文件受到QFE的影响，并在每个文件上使用System.Diagnostics.FileVersionInfo.GetVersionInfo(path)并比较版本号。

编辑：我觉得有一种方法来检查注册表中的卸载信息为好，但如果QFE真的成为可能报告漏报
