c中确定已安装给定QFE /补丁的最佳方法是什么？

解决方案

回答

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：我认为也有一种方法可以检查注册表中的卸载信息，但是如果QFE曾经成为Service Pack或者汇总包的一部分，则可能会报告错误的否定消息。

使用WMI并检查Win32_QuickFixEngineering枚举。

从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

HotFixID是我们要检查的内容。

这是我系统上的输出：
