WMI 查询系统中安装的修补程序列表? [英] WMI Query for list of hotfixes installed in a system?

问题描述

我正在编写一个 perl 脚本，它会列出我系统中安装的修补程序，并在开始我的程序之前检查是否有任何先决条件的修补程序不可用；

所以我需要能够枚举系统中的修补程序列表；这里 提到了使用 wmic 生成 html 文件.是否可以通过 WMI 查询执行此操作?

解决方案

我自己已经找到了答案！！此处提供了一个 vbscript 选项.>

perl 版本是这样的..

use Win32::OLE qw( in );我的 $machine = ".";my $WMIServices = Win32::OLE->GetObject ( "winmgmts:{impersonationLevel=impersonate,(security)}//$machine/root/cimv2") ||死不能调用getobject"；我的 $HotFixCollection = $WMIServices->ExecQuery ( "select * from Win32_QuickFixEngineering" ) ||die "查询失败";foreach 我的 $hotfix ( in( $HotFixCollection )){$hotfixID = $hotfix->{HotFixID};打印 "修补程序 ID 是 $hotfixID \n";}

I am writing a perl script that will list the hotfixes installed in my system and check if any pre-requisite hotfixes are not available before beginning my program;

So I need to be able to enumerate the list of hotfixes in the system; Here there is a mention of using wmic to generate a html file. Is it possible to do this via a WMI query?

解决方案

I have figured out the answer for this myself!! There is a vbscript option provided here.

The perl version goes like this..

use Win32::OLE qw( in );
my $machine = ".";
my $WMIServices = Win32::OLE->GetObject ( "winmgmts:{impersonationLevel=impersonate,(security)}//$machine/root/cimv2" ) || die "cant call getobject";
my $HotFixCollection = $WMIServices->ExecQuery ( "select * from Win32_QuickFixEngineering" ) || die "Query Failed";

foreach my $hotfix ( in( $HotFixCollection )){
 $hotfixID = $hotfix->{HotFixID};
 print "Hotfix id is $hotfixID \n";
}
