OsInfo - Operating System Info

Compare operating system versions, check if OS is 32/64-bit and what service pack is installed. Targets .NET 3.5 Client. Supports Windows 8.1 and all previous Windows versions.

NuGet

To install, type Install-package OsInfo into Package Manager Console in Visual Studio or visit the nuget page.

Examples

public void PrintCurrentOs()
{
    OperatingSystem currentOs = Environment.OSVersion;
    Console.WriteLine("Current OS: " + currentOs);
    Console.WriteLine("Service pack: " + (currentOs.GetServicePackVersion() ?? (object)"(null)"));
    
    // In .NET 4.5+ you can use Environment.Is64BitOperatingSystem instead
    Console.WriteLine("Is 64-bit: " + currentOs.Is64Bit()); 
    
    Console.WriteLine();
    Console.WriteLine("Greater than or equal to XP     : " + currentOs.IsGreaterThanOrEqualTo(OsVersion.WinXP));
    Console.WriteLine("Greater than or equal to Vista  : " + currentOs.IsGreaterThanOrEqualTo(OsVersion.Vista));
    Console.WriteLine("Greater than or equal to Win7   : " + currentOs.IsGreaterThanOrEqualTo(OsVersion.Win7));
    Console.WriteLine("Greater than or equal to Win8   : " + currentOs.IsGreaterThanOrEqualTo(OsVersion.Win8));
    Console.WriteLine("Greater than or equal to Win8.1 : " + currentOs.IsGreaterThanOrEqualTo(OsVersion.Win8Update1));
    Console.WriteLine();
    Console.WriteLine("Equal to Win8                   : " + currentOs.IsEqualTo(OsVersion.Win8));
    Console.WriteLine("Equal to Win7                   : " + currentOs.IsEqualTo(OsVersion.Win7));
    Console.WriteLine();
    Console.WriteLine("Less than or equal to Win8      : " + currentOs.IsLessThanOrEqualTo(OsVersion.Win8));
    Console.WriteLine("Less than or equal to Win7      : " + currentOs.IsLessThanOrEqualTo(OsVersion.Win7));
    Console.WriteLine();
    Console.WriteLine("Less than Win8                  : " + currentOs.IsLessThan(OsVersion.Win8));
    Console.WriteLine("Less than Win7                  : " + currentOs.IsLessThan(OsVersion.Win7));
}
