从Registry中筛选已安装的应用程序，仅显示“程序和功能”中的列表

Question

我可以轻松地从HKLM \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows \ CurrentVersion \ Uninstall的注册表位置提取系统上的应用程序列表，但我获取的应用程序列表远远大于显示的列表程序和功能。

例如，在我设置的测试系统上，它显示了程序和功能中的14个条目，但是当我从上面显示的注册表项中提取应用程序时，我得到了35个应用程序。

有没有办法将此列表过滤到只有程序和功能中显示的14个条目？

这是我的代码，以防它有用：

    Dim _AppList As New ArrayList

    Sub New()

        If CheckOSfor64() Then GetKeyValues("SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\", RegistryHive.LocalMachine)
        _AppList.Sort()
