در قسمت نمونه برنامه ها در پست 20 ام یک برنامه هست که مانع از تایپ بعضی از کلیدهای صفحه کلید میشه، اون نمونه برنامه رو نگاه کنید شاید بدرد بخوره.
برای اینکه مانع بشید کلیدهای Ctrl+ESC یا کلید Win فشرده بشه تا منوی استارت از طریق صفحه کلید باز نشه.

برای حذف کلید Winkey
ابتدا یه کلاس بساز و این کد رو در آن قرار بده

و بعد در فرمت این متغیر رو به صورت عمومی تعریف کن


globalKeyboardHook gkh = new globalKeyboardHook();حالا این کد ها رو هم توی برنامه ی خودت قرار بده


private void Form1_Load(object sender, EventArgs e) {
gkh.HookedKeys.Add(Keys.RWin);
gkh.HookedKeys.Add(Keys.LWin);
gkh.KeyDown += new KeyEventHandler(gkh_KeyDown);
gkh.KeyUp += new KeyEventHandler(gkh_KeyUp);
}

void gkh_KeyUp(object sender, KeyEventArgs e) {
lstLog.Items.Add("Up\t" + e.KeyCode.ToString());
e.Handled = true;
}

void gkh_KeyDown(object sender, KeyEventArgs e) {
lstLog.Items.Add("Down\t" + e.KeyCode.ToString());
e.Handled = true;
}الان کلید Win Key غیر فعال است البته این رو هم بگم که میتونی هر کلیدی رو در List زیر وارد کنی تا غیر فعال بشه



gkh.HookedKeys.Add(Keys.RWin);
