DirectoryInfo Error / Getting all directories in a given path

I'm using the following code which appears as if it should get all the directories on my hard drive (or any given path).  The problem is, even as an admin of my machine there are protected directories that I apparantly don't have access too and it throws an access exception on the for each line (The specific error is:  Access to the path 'c:\WINDOWS\Cannot delete for whatever reason\8fae693e482ad5d9c6a7b4e423dcd452\sp1' is denied.).  Is there an obvious solution I'm missing without writing more code to recurse manually?

I'm less concerned with the fact that I don't have access to certain directories, that will happen in how I'm going to use this anyway.  I'd prefer it just skipped those directories and moved on (the GetDirectories halts though on this exception).

        Dim rootDi As New DirectoryInfo("c:\")

        For Each di As DirectoryInfo In rootDi.GetDirectories("*", SearchOption.AllDirectories)
            Label1.Text = di.FullName
            Application.DoEvents()
        Next

Nope some folders are off limits, your best option would be to do some manual recursion like

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        GetDirectories("C:\")
    End Sub

    Private Sub GetDirectories(ByVal Path As String)
        Try
            Dim arrDir() As String = System.IO.Directory.GetDirectories(Path)
            For Each eleDir As String In arrDir
                ListBox1.Items.Add(eleDir)
                Application.DoEvents()
                GetDirectories(eleDir)
            Next
        Catch ex As Exception

        End Try
    End Sub

That appears to do the trick since it errors out on just directories it can't read.  Thanks for a quick and correct response.
