Having some trouble when opening chrome browser with Selenium ChromeDriver

Question

I use Selenium ChromeDriver to open chrome browser and load a site into it programmatically.

I install selenium & ChromeDrive from this NuGet

Install-Package Selenium.WebDriver -Version 3.141.0 Install-Package Selenium.WebDriver.ChromeDriver -Version 77.0.3865.4000

I have some questions:

if target pc has no chrome browser installed then how can i capture it by ChromeDriver ? is it possible?
when i am opening chrome browser by ChromeDriver instance then browser is opening chrome browser with a site but another CUI window is getting opened which i do not want to visible or i want to hide this CUI window. if it is not possible then how could i open this CUI window in minimize state?

a sample CUI window screen shot attached below when i work with FirefoxDriver. the same occur when i work with ChromeDriver instance.
when i executing this code chromeDriver.Close(); then opened chrome browser is getting closed but CUI window is still open. so if i click 5 times on open button then 5 CUI window is getting open along with 5 chrome browser instance which i had to close manually ....which i do not want to manually close it rather i want to close it when browser will be closed....how to achieve it ?
how to capture from code that opened chrome browser is close by this code chromeDriver.Close(); or if user click on cross button of chrome browser to close it?
how to open a new tab in already opened chrome browser instead of opening new chrome browser instance. if no chrome browser is open at all then new chrome browser will be open...how to achieve it by code. this below code opening new chrome browser always....what to change there for my point 5
```
chromeDriver = new FirefoxDriver(options);
chromeDriver.Navigate().GoToUrl("https://www.google.com");
```
another issue occur when i work with chrome driver that. it open chrome browser but a notification appear on browser like Chrome is being controlled by automated test software

I search google to hide it and found people said to use this option
```
options.setExperimentalOption("excludeSwitches", new String[] { "enable-automation" });
```
at my end this function does not available setExperimentalOption so what to do?

Please answer point wise with sample code.

For question 2,3 you can use below code (use DriverService.Dispose(); to manually dispose driver service) :

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace MyProject
{
    public class Browser : IDisposable
    {
        bool disposed = false;    
        IWebDriver Driver;

        public Browser()
        {
            //Chrome Driver copied on startup path                
            ChromeDriverService driverService = ChromeDriverService.CreateDefaultService(Application.StartupPath, "chromedriver.exe");

            //hide driver service command prompt window
            driverService.HideCommandPromptWindow = true;
            ChromeOptions options = new ChromeOptions();

            //hide browser if you need              
            //options.AddArgument("headless");
            //or this to hiding browser
            //options.AddArgument("--window-position=-32000,-32000");

            //On offer Dona bhatt for disable automated test notification
            options.AddExcludedArgument("enable-automation");
            //options.AddArgument("disable-infobars");

            Driver = new ChromeDriver(driverService, options);
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }

        protected virtual void Dispose(bool disposing)
        {
            if (disposed)
                return;

            if (disposing)
            {
                Driver.Close();
                Driver.Quit();
                Driver.Dispose();

                DriverService.Dispose();
            }

            disposed = true;
        } 

        //this method for navigation
        public string Navigate(string url)
        {
            string page = string.Empty;
            try
            {
                Driver.Navigate().GoToUrl(url);
                page =Driver.PageSource;
            }
            catch
            {

            }
            return page;
        }

        //this method for wait to an element be visible by element ID
        private void WaitUntilLoad(string id, int timeOut)
        {
            WebDriverWait waitForElement = new WebDriverWait(Driver, TimeSpan.FromSeconds(timeOut));
            try
            {
                waitForElement.Until(ExpectedConditions.ElementIsVisible(By.Id(id)));
            }
            catch (WebDriverTimeoutException e)
            {

            }
        }
     } 
 }

Use this class:

using(Browser brw=new Browser())
{
    string pageSource=brw.Navigate("My URL");
}
