How to free and release closed Chrome browsers' memories in Selenium?

I wrote a multi-threading automation that uses a lot of multiple Chrome browsers (can be repeatedly) with Selenium and C#.

I tried to use everything including "--incognito", "--disable-application-cache", waiting a second before opening another browser, driver.Close(), .Quit() and .Dispose(). Here's the code sample:

IWebDriver[] drivers = new IWebDriver[AUTOMATION_NUM];
int QUEUE_BROWSERS_TO_OPEN = 0;

Thread mainThread = new Thread(() =>
{
    for (int i = 0; i < AUTOMATION_NUM && !EXIT; i++)
    {
        ...
        Thread driverThread = new Thread(() => {
            ...
            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.AddArguments("--incognito", "--disable-application-cache"); // headless or non-headless

            IWebDriver driver = drivers[instance];
            driver = new ChromeDriver(chromeService, chromeOptions, TIMEOUT_FROM);
            ...
            ++QUEUE_BROWSERS_TO_OPEN;
            ...
            driver.Close();
            driver.Quit();
            driver.Dispose();
        });

        _machineThreads.Add(driverThread);
        driverThread.IsBackground = true;
        driverThread.Start();

        while (i < AUTOMATION_NUM && !EXIT)
        {
            Thread.Sleep(5000);

            if (QUEUE_BROWSERS_TO_OPEN > 0 && BROWSERS_OPEN < BROWSER_NUM)
                --QUEUE_BROWSERS_TO_OPEN;
        }
    }

    Thread endThread = new Thread(() =>
    {
        foreach (Thread machineThread in _machineThreads)
            machineThread.Join();

        ...
    });
    endThread.Start();
});
mainThread.Start();

And have suggested my client to kill all "chromedriver.exe" processes by clicking a button to execute this code:

Process[] chromeDriverProcesses = Process.GetProcessesByName("chromedriver");

foreach (var chromeDriverProcess in chromeDriverProcesses)
    chromeDriverProcess.Kill();

But my client is still saying that the closed and finished automated browsers' memories are still there?

Closed Chrome browsers' memories

Any working solution how can I prevent my client's high-end PC from restarting to free up Chrome memory or from being frozen before using the automation again? Any other alternative?

There is command to kill all open browsers windows(chrome.exe) and chrome driver process associated with that browser window (chromedriver.exe)

To kill chrome driver process

string strCmdText;
strCmdText= "TASKKILL /f  /IM  CHROMEDRIVER.EXE";
System.Diagnostics.Process.Start("CMD.exe",strCmdText);

To kill chrome browser window

string strCmdText;
strCmdText= "TASKKILL /f  /IM  CHROME.EXE";
System.Diagnostics.Process.Start("CMD.exe",strCmdText);

For more information refer this and this
hope this helps...
