Hello Khurram Aziz,
Thank you for posting question on Microsoft Windows Forum!
Based on your query of how to disable top bar in Hyper-V client in full screen permanently as well as the provided screenshot. Well! To permanently disable the top bar so touch inputs never trigger it, you connect to your Windows 7 VM using Remote Desktop Connection (mstsc.exe) instead of the Hyper-V console. You can follow the steps below.
- Inside your VM, open sysdm.cpl (System Properties) > Remote tab > Select Allow connections from computers running any version of Remote Desktop. Launching MSTSC on Windows 11 host by pressing Win + R, type mstsc, and press Enter. Click Show Options, navigate to the Display tab, and uncheck Display the connection bar when I use the full screen. Then enter the IP address of your Windows 7 VM and click Connect. Please note: Once connected in full screen without the bar, press Ctrl + Alt + Break or Ctrl + Alt + Pause on an external keyboard if you ever need to exit full screen mode.
Another suggested workaround is on your Dell tablet, start the Windows 7 VM in Hyper-V Manager. Select View → Full Screen Mode. Move your finger/mouse to the top of the screen so the bar appears. On the left side of the bar, find the pin icon; it is the icon visible in your screenshot. Tap the pin icon once. The icon should change to the un-pinned state. Then move your finger away from the top and wait about 5 seconds. The toolbar should then disappear automatically.
