如何检查是否已从 c# 安装了 Windows QFE/补丁? [英] How do I check that a Windows QFE/patch has been installed from c#?

问题描述

在 c# 中确定是否已安装给定 QFE/补丁的最佳方法是什么?

解决方案

使用 WMI 并检查 Win32_QuickFixEngineering 枚举.

来自 TechNet:

strComputer = "."Set objWMIService = GetObject("winmgmts:" _&"{impersonationLevel=impersonate}!\\" &strComputer &"\root\cimv2")设置 colQuickFixes = objWMIService.ExecQuery _(从 Win32_QuickFixEngineering 中选择 *")对于 colQuickFixes 中的每个 objQuickFixWscript.Echo "计算机:" &objQuickFix.CSNameWscript.Echo "描述:" &objQuickFix.DescriptionWscript.Echo "Hot Fix ID: " &objQuickFix.HotFixIDWscript.Echo "安装日期:" &objQuickFix.InstallDateWscript.Echo "安装者:" &objQuickFix.InstalledBy下一个

HotFixID 是您要检查的内容.

这是我系统上的输出:

What's the best way in c# to determine is a given QFE/patch has been installed?

解决方案

Use WMI and inspect the Win32_QuickFixEngineering enumeration.

From 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

The HotFixID is what you want to examine.

Here's the output on my system:
