Answer 1

The background of a Lable is inherited from its container Background.

You can set a different Parent Container using the [Control].Controls.Add() method, which sets the Parent property to the new Container (you could also modify the .Parent property directly).

You can re-define your Label's Parent in the Form constructor (the Public Sub New() of a Form - insert the code after InitializeComponent()) or in the Form.Load() event handler.
Here I'm showing both, pick one:

Public Sub New()

    InitializeComponent()

    PictureBox1.Controls.Add(Label1)
    'Re-define the Label.Location if required
    Label1.Location = New Point(0, 0)
End Sub

The same thing in the Form.Load() event:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    PictureBox1.Controls.Add(Label1)
End Sub

As an alternative, you could use the PictureBox .Paint() event's e.Graphics to simply Draw the same Text.

Private Sub PictureBox1_Paint(sender As Object, e As PaintEventArgs) Handles PictureBox1.Paint
    Using TextBrush As SolidBrush = New SolidBrush(Me.ForeColor)
        e.Graphics.DrawString("BITS Registration ID", Me.Font, TextBrush, New Point(5, 5))
    End Using
End Sub
