VB.Net and Installed Operating System Type (OEM or VL)

Question

Hi,

Currently I am checking the Windows 10 license type if it's Volume License (VL) or Pre-Installed (OEM) with slmg.vbs from a command prompt, like this:

Is it possible to check the same with VB.Net? If its OEM, show form1, if its VL show form2?

Answer 1

You can use WMI to get the string (that's what slmgr does). For example,

        Dim LicQuery As SelectQuery = New SelectQuery("SELECT * From SoftwareLicensingProduct")
        Dim Lic As ManagementObjectSearcher = New ManagementObjectSearcher(LicQuery)
        For Each l In Lic.Get()
            Dim s As String = l("Description")
            Console.WriteLine(s)
        Next

I'll leave it to you to parse the returned string. :)

Answer 2

Yes you can. You could convert the VBScript file you referenced to VB as it is mostly VB you'd just have to make some adjustments.

Alternatively look at what the script is doing and just do the same in VB. Most if it is looking at registry entries from what I can see.
