Sony Hotkey Server – HKSERV.EXE
HKSERV.EXE comes preinstall on many Sony Notebooks including the Sony VAIO, Sony PCGF400, and SR7K Super Slim Notebooks. It is a keyboard utility called the Sony Hotkey Server. This can be removed but doing so will disable support for some of the Fn-Function-Key combinations.
Because we were not able to find major problems or conflicts with this utility, we'd recommend leaving it in place.
