Sometimes some system sounds are missing sfc /scannow corrupted files

[Xomuz]

Hello everybody

I have a strange problem because sometimes about 1 in 3-5 times when I startup my pc some system sounds are missing
From what I've noticed missing:
startup sound
click sound when navigating folders
warning sounds when you exit from unsaved document in notepad for example
shutdown sound
and other system sounds works normally

Like I said Windows Default Sound Scheme is alright because it only happens about 1 in 3-5 system startup

and I tried sfc /scannow but it didn't help and shows many errors which I don;t know what they are
I repeated scan few times without success
I have attached my scsn log
Thanks in advance for any help

If you want to resolve the System File Check errors yourself, you need to research each error, understand its source and learn how the system works. It takes some work.

Did you reboot after each sfc /scannow?

Sometimes the repair is done during the boot process.
