Find what windows version is on a specified drive

Question

I want to find what OS version (e.g.: Window 7 Pro) is on drive D: without digging through D:\Windows\System32\license.rtf

Is there a class within System.Management namespace that will let me find OS Versions on a specified local drive letter?

Answer 1

    //This will help you detect the version of the OS for NT based system, if ntoskrnl.exe doesnt exist its ME/95/98
    var DriveLetter = "D"; //D drive.
    var pathTontoskrnl = string.Format("{0}:\\{1}", DriveLetter, "\\Windows\System32\ntoskrnl.exe");
    if (!File.Exists(pathTontoskrnl))
    {
        Console.WriteLine("Windows ME/95/98");  
    }
    var versionInfo = FileVersionInfo.GetVersionInfo(pathTontoskrnl);
    string version = versionInfo.ProductVersion; 
    if ( version.StartsWith("5.1") )
    {
        Console.WriteLine("XP");
    }
    //4.x: NT 4.x
    //5.0: Win2k
    //5.1: WinXP
    //5.2: Win2003 or XP-x64
    //6.0: WinVista
    //6.1: Win7
    //6.2; Win8
    //6.3: Win8.1
    //6.4: Win10 ??? (not sure)
