here is the step to enable ot startup sound. click on start. in the
searchbox type control panel & click on sounds. Under this click on
the sounds tab & check the box to play startup sound. I am sorry, I
amnot really aware as to how to enable ot log off sound.

Apparently, there is a way to set up the log-off, but the reliability is inconsistent, even if you set it up; also, the setup is not easy. If you're bolder and more motivated than I am, though, here's a link to some chatter about it--though, I wasn't able to convert to a hyperlink, so you'll have to copy/paste it into your browser:

Add Log On, Log Off and Shut down sounds to Windows 11

Also, from what I've heard on other lists for blind folks, the sound doesn't indicate that the computer is actually shutting down--you could still end up only partly shut down, for instance, if, for some reason, Windows wouldn't let you close out due to another program not shutting down first; and if, for some reason, JAWS isn't cooperating and you don't hear about that, the only clue you'd get is that the back fan is still whirring. . I have heard of some people using a small USB fan as a sound cue to when a computer actually is completely shut down, which, to me, would be a much more reliable indicator. Finally--and this only works in a quiet room and/or if you don't have a hearing issue--you will hear the fan in the back of the computer stop whirring, when the computer is shut down totally. HTH!

An identity would seem to be arrived at by the way in which the person faces and uses his experience.

There is no default log off sound for Windows 10 or 11 as there was in Windows 7 and earlier.  Don't even try to hack the registry or follow some convoluted series of instructions to create a log off sound unless you are an advanced techie and have sighted help on hand in case you screw things up. The most reliable way to tell for sure that your PC has powered off is to connect a small, inexpensive USB powered cooling fan.  When the fan stops spinning, then your PC has powered off.  This will work with almost any PC, and the little fan  will create a gentle and refreshing breeze.
