Displaying a tap on the caps fn screen, etc.how to remove it.

@EDAIVER2020

The graphical overlays you see when pressing Caps Lock, Fn + Win, Fn + F8, etc., are typically part of the OEM utility software preinstalled by your laptop manufacturer—in your case, Acer. These overlays are often managed by programs like:
Acer Quick Access
Acer Care Center
Acer Launch Manager (on older models)

To disable or remove these graphical pop-ups. Disable via Acer Quick Access (if installed)
Press Windows + S and type Quick Access. Open Acer Quick Access. Look for settings like, “Function key display” “On-Screen Display (OSD)” Disable them.

Press Windows + R, type appwiz.cpl, and press Enter. Look for the above mentioned programs, right-click and choose Uninstall if you don’t need them.

Removing these apps may also disable hotkey functionality (like airplane mode, brightness, etc.)—only do this if you're sure. If you'd like to keep the functionality but hide the pop-ups, some utilities (like Quick Access) allow this in their settings, so always check inside the app first.
