Anyone knows how to retrieve windows product key using vb.net? I have got a sample to retrieve Windows XP product key, but i also need to retrieve the product key for others, ie: Win 2k, Win 98...
Here's the sample to retrieve WinXP product key:
Public Function GetXPKey() As String
Dim RegKey As RegistryKey = _
Registry.LocalMachine.OpenSubKey("Software\Microsoft\Windows NT\CurrentVersion", False)
Dim bytDPID() As Byte = RegKey.GetValue("DigitalProductID")
Dim bytKey(14) As Byte
Array.Copy(bytDPID, 52, bytKey, 0, 15)
Dim strChar As String = "BCDFGHJKMPQRTVWXY2346789"
Dim strKey As String = ""
For j As Integer = 0 To 24
Dim nCur As Short = 0
For i As Integer = 14 To 0 Step -1
nCur = CShort(nCur * 256 Xor bytKey(i))
bytKey(i) = CByte(Int(nCur / 24))
nCur = CShort(nCur Mod 24)
Next
strKey = strChar.Substring(nCur, 1) & strKey
Next
For i As Integer = 4 To 1 Step -1
strKey = strKey.Insert(i * 5, "-")
Next
Return strKey
End Function
Thanks.
