我可以轻松地从 HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall 的注册表位置中提取系统上的应用程序列表,但我返回的应用程序列表比程序和程序中显示的列表大得多特征。

例如,在我设置的一个测试系统上,它在程序和功能中显示了 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仅显示在程序和功能中的 14 个条目?

这是我的代码以防万一:

Class InstalledApps
    Dim _AppList As New ArrayList

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

    Sub New(SaveFileLocation As String)
        GetKeyValues("SOFTWARE\Microsoft\Windows\Currentversion\Uninstall", RegistryHive.LocalMachine)
        GetKeyValues("SOFTWARE\Microsoft\Windows\Currentversion\Uninstall", RegistryHive.CurrentUser)
        If CheckOSfor64() Then GetKeyValues("SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\", RegistryHive.LocalMachine)
        _AppList.Sort()
        SaveFile(SaveFileLocation)
    End Sub

    Public ReadOnly Property getAppList As ArrayList
        Get
            Return _AppList
        End Get
    End Property

    Private Sub SaveFile(Path As String)
        Try
            IO.File.Delete(Path)

            Using newFile As StreamWriter = New StreamWriter(Path)
                newFile.AutoFlush = True
                For Each item As String In _AppList
                    If item.Contains("(KB") Then Continue For
                    newFile.WriteLine(item)
                Next
            End Using

            Else
                Return False
            End If

            Return False
        End Try
    End Function

    Private Sub GetKeyValues(ByVal RegKey As String, ByVal Hive As Microsoft.Win32.RegistryHive)
        Dim rk As RegistryKey = Nothing 'Main Keys
        Dim sk As RegistryKey = Nothing 'Sub Keys
        Dim name As String = String.Empty

        Try
            Select Case Hive
                Case RegistryHive.CurrentUser
                    rk = Registry.CurrentUser.OpenSubKey(RegKey)
                Case RegistryHive.LocalMachine
                    rk = Registry.LocalMachine.OpenSubKey(RegKey)
            End Select

            If rk Is Nothing Then Exit Sub

            For Each skn As String In rk.GetSubKeyNames
                If skn = Nothing Then Continue For
                sk = rk.OpenSubKey(skn)

                If sk.ValueCount = 0 Then Continue For

                name = GetSubKeyValue(sk, "DisplayName")

                'If empty skip
                If name = String.Empty Then Continue For

                'Check for Duplicate before adding
                If Not _AppList.Contains(name) Then _AppList.Add(name)

            Next
        Catch ex As Exception
            errorLogs.Add(ex)
        Finally
            If Not rk Is Nothing Then rk.Close()
            If Not sk Is Nothing Then sk.Close()
            rk = Nothing
            sk = Nothing
        End Try

    End Sub

    Private Function GetSubKeyValue(ByVal MainKey As RegistryKey, ByVal ValueName As String) As String
        Try
            If Not MainKey Is Nothing Then
                Dim t As String = MainKey.GetValue(ValueName)
                If t = Nothing Then Return String.Empty Else Return Trim(t)
            Else
                Return String.Empty

        Catch ex As Exception
            Return String.Empty
