Answer 1

来自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

您要检查HotFixID。

这是我系统上的输出：

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

编辑：我认为有一种方法可以检查注册表中的卸载信息，但是如果QFE成为可能报告错误否定的Service Pack或汇总包的一部分

如何检查是否已从c＃安装了Windows QFE /补丁？
