Devi editare il file user.xm per fare in modo che il programma ignori la hotkey, in questo modo sarà Windows ad intercettare la pressione del tasto e non SetPoint
1- Open TaskManager and close SetPoint.exe and KHALMNPR.exe
2- Backup user.xm, just in case.
3- Edit user.xml fround at: (%USERPROFILE%\AppData\Roaming\Logitech\SetPoint (copy and paste in the address bar of a folder, or paste in the Start Screen and hit Enter)
4- Go to down to the media keys you want to change so that it uses Windows 8 notifcation and control support, and not SetPoint, replace the code for each button as follows:
Volume Down Key:
<Button Number="786666" Name="Volume Down Controller">
<Param IconLoc="" Type=""/>
<Trigger class="ButtonPress">
<Param Button="786666" EventType="100663297" FirstRepeatDelay="600" RepeatDelay="50" Silent="0" Type="0"/>
<TriggerState Name="ButtonDownUp" HandlerSet="VOLUMEDOWN">
<Handler class="KeystrokeAssignment">
<Param DisplayName="Volume Down" LParam="0" Modifier="0" VirtualKey="174"/>
</Handler>
</TriggerState>
</Trigger>
</Button>
Volume Up Key:
<Button Number="786665" Name="Volume Up Controller">
<Param IconLoc="" Type=""/>
<Trigger class="ButtonPress">
<Param Button="786665" EventType="100663297" FirstRepeatDelay="600" RepeatDelay="50" Silent="0" Type="0"/>
<TriggerState Name="ButtonDownUp" HandlerSet="VOLUMEUP">
<Handler class="KeystrokeAssignment">
<Param DisplayName="Volume Up" LParam="0" Modifier="0" VirtualKey="175"/>
</Handler>
