One way is to plug headphones into your system or mute it when you boot up, no doubt both require you to proactively do something to counter it. It can be much convenient to just turn it Off.
Windows 10 has a way to do this, you can turn off the startup sound via the default sound settings.

Under Control Panel select the ‘Hardware and Sound’ option.
In the Hardware and Sound window, select ‘Sound’.
From the new window that open, go to the ‘Sounds’ tab
Below ‘Program Events’ section, you will see ‘Play Windows Startup Sound’ and a checkbox right before that. Uncheck it and click ‘Ok’.

In Registry Editor, from the left sidebar navigate to HKEY_CURRENT_USER\AppEvents\EventLabels
Now you are going to make some small change inside the EventLabels key. To turn off shutdown sound or, as Windows call it, “System Exit”.
Under the EventLabels key from the left side of Registry Editor, select the “SystemExit” subkey, then double-click the ExcludeFromCPL value.
The value “0” means that the action is included in the properties of the sound under control panel, the value is 1 means that the action is excluded from the Control Panel. Change the value to 1 to disable the sound from the control panel and then click “OK.”
