Hi Khurram Aziz,
While you can click the pin icon to make it auto-hide, the Hyper-V client is hardcoded to drop this bar down whenever touch input is detected at the top edge of the screen. This is a built-in safety feature designed to prevent users from getting stuck in full-screen mode without a keyboard. There is no registry modification or Hyper-V setting that can permanently disable this specific touch trigger.
To get a completely clear screen on your Dell tablet, you must switch to using the Windows Remote Desktop Connection tool to access your virtual machine. First, enable Remote Desktop within your Windows 7 guest operating system and locate its IP address. On your Windows 11 host, open the Start menu and type mstsc to launch Remote Desktop Connection. Click on Show Options, select the Display tab, and clear the checkbox next to Display the connection bar when I use the full screen. Connect to your Windows 7 IP address through this interface, and the top bar will be permanently disabled, preventing it from dropping down over your buttons.
