YOu can do it with WMI

'ref NET   System.Management

Public Class Form1
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "
#End Region

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim strComputer As String = "."
        Dim objWMIService As Object = GetObject("winmgmts:" _
            & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
        Dim colBIOS As Object = objWMIService.ExecQuery _
            ("Select * from Win32_BIOS")
        Dim objBIOS As Object
        Dim msg As String
        Dim i As Integer

        For Each objBIOS In colBIOS
            msg &= "Build Number: " & objBIOS.BuildNumber & _
            " Name: " & objBIOS.Name & _
            " Release Date: " & objBIOS.ReleaseDate & _
            " Serial Number: " & objBIOS.SerialNumber & _
            " SMBIOS Version: " & objBIOS.SMBIOSBIOSVersion & _
            " SMBIOS Major Version: " & objBIOS.SMBIOSMajorVersion & _
            " SMBIOS Minor Version: " & objBIOS.SMBIOSMinorVersion & _
            " SMBIOS Present: " & objBIOS.SMBIOSPresent & _
            " Status: " & objBIOS.Status & _
            " Version: " & objBIOS.Version
            For i = 0 To UBound(objBIOS.BiosCharacteristics)
                msg &= " BIOS Characteristics: " & _

Take a look at the activelock activeX Control

Just drop it on you Form and a few lines of code will allow you to even register and detect Date/Time changes

And best of all... Its free and open source


Here you go ;)

Hope this helps

This is the Windows time, it is shorter and simpler and I doubt someone will change thier windows date/time to avoid purchasing a product.

Dim t As DateTime = Now
