Find windows folder programatically in c#

Question

I am writing a program to kill and restart explorer but I don't want to hard code the location becuase some people install windows in diffrent places (for example i found someone who had it installed in the d:\ drive where the C:\ drive did exist but had nothing installed on it)

I tried looking under Environment.SpecialFolder. but I don't see a "windows" option under that

anyone know what the best way to do this is.

Try these:

Environment.GetEnvironmentVariable("SystemRoot")

Environment.GetEnvironmentVariable("windir")

To simply kill and restart Windows Explorer you wouldn't need the path to the system folder as this is already included in the PATH environment variable (unless the user messed with it).

That short program will kill all explorer.exe instances and then restart explorer.exe:

static void Main(string[] args)
{
    foreach (Process process in Process.GetProcessesByName("explorer"))
    {
        if (!process.HasExited)
        {
            process.Kill();
        }
    }
    Process.Start("explorer.exe");
}
