<p>If you need to automate the process of enabling/disabling the sound/volume control icon in system tray on Windows XP, here&#8217;s how you can do it easily.</p>
<p><!--more--></p>
<p>Open the registry editor and navigate to the following key:</p>
<p><strong>HKCU\Software\Microsoft\Windows\CurrentVersion\Applets\Systray</strong></p>
<p>You should have a <strong>DWORD</strong> called <strong>Services</strong>. If Services value is set to <strong>1F</strong>, the volume control will be visible in system tray. To make icon disappear, the value should be changed to <span style="color: #003366;">1B<strong>.</strong></span></p>
<p><strong>TIP</strong>: I&#8217;ve also noticed that if you set the Services <strong>DWORD</strong> key to value <strong>1E</strong>, you will get the same result as for <strong>1F</strong>. I&#8217;m not quite sure what is the difference between those two values as both give the same result.</p>
<p>You can make a registry key and publish it via Group Policy to distribute your setting across your domain.</p>
<p>Both registry keys are available for download below:</p>
