One of the annoying things M$ have done in Windows 10 is hide the logon/logoff sounds – all you can do now is turn the initial startup sound ON or OFF, not much good for power users.
I have made a small .reg file that turns them back on in Control Panel.
DOWNLOAD HERE Right (Mouse Click and select “Save Link As” save it to desktop so it’s easy to find, double click it select YES at the prompt), you will now see that they now appear back where they should be 🙂 No reboot required.
I hope this helps some of you.
