A Sony kandy Windows tablets, there are a few years age, now looks like the Volume of the Volume button + buttons, as has been holding down don't let go, cause the system directly received a similar Volume UP, Volume has been automatically increases to 100, down immediately and automatically increases to 100, the window of the desktop has been Volume 100,

Should not system problem, because recently new Win10 system installation, performance is the same, at present, using the method of a force is by modifying the registry, edit the Scancode Map, maps the system continues to receive E030 button code is 0000, let it fail,

In so doing, the problems in the automatic adjust volume, but the background is still continuing to receive key event, the system still has some other abnormality, such as open new program or a pop-up window, the window will not automatically to the front, and some MouseOn type menu can't normal open,

Excuse me is there a method from the aspect of hardware block to control the volume of physical buttons?
