this code enable turn pc volume how turn down pc volume me

these tested , work here - keycodes in microsoft link in comment below.

volume control up.bat

@if (@a==@b) @end /*  :: batch portion  @echo off  cscript /e:jscript "%~f0"   :: jscript portion */  var shl = new activexobject("wscript.shell"); (var i=0; i<5; i++) {     shl.sendkeys(string.fromcharcode(0xaf)); }

volume control down.bat

@if (@a==@b) @end /*  :: batch portion  @echo off  cscript /e:jscript "%~f0"   :: jscript portion */  var shl = new activexobject("wscript.shell"); (var i=0; i<5; i++) {     shl.sendkeys(string.fromcharcode(0xae)); }

original answer follows:

according comment kul-tigin below, correct code should ae

shl.sendkeys(string.fromcharcode(0xaf));

you can use utility show keycodes when press , down volume buttons, assuming find utility returns keycode them.

the utility have show af hex or 175 decimal up volume key, , should show correct number down volume key.
