I use Win10 Settings Sound Control Panel to set system sounds for events and other things.
I suppose we all use our Windows devices differently.
With my Dell 5770 laptop I open the lid press the start button then show my finger print and Windows 10 is ready to go, no sounds, no fuss. I just timed it ... 20 secs.
This happens because I never shut it down. When I want to stop the laptop I simply close the lid. The laptop then 'hibernates' which means it save everything I was doing to the SSD/HDD and then switches off the screen and powers off. Open the lid show finger print and continue where I left off.
About once a week I shut the laptop down and then I have to save anything I was doing. From a shut down it starts as mentioned above but takes slightly longer.
With my Acer desktop computer I do power down so with start up it has to load drivers etc and it slightly slower about 40 secs. It just wants a 4 digit pin number to prove it's me. I can hibernate it which makes it a few seconds quicker starting up.
I use a Microsoft account so get full sync. My 'home network' is a 32Gb flash drive plugged into the router.
I also use an Apple iPad which you have to use exactly as Apple wants you to. Put my finger on the button, it reads my finger print to prove it's me, and is on in 5 secs. It sleeps when I'm not using it and syncs with my Win 10 devices.
All my email account auto forward to it and 'dings' to let me know.
But we all use them differently ... even using different internet browsers ...
