This feature seems to have been added in PowerShell version 5.1, as I don't find it on my laptop still running 5.0.
When pressing Backspace in PowerShell, it will emit a 'beep' sound if there is no (more) text to delete. This is quite annoying if you accidentally hold down the key too long, as the sound will keep going for a short while after you release it.
I found this Super User question which suggests to disable the Beep service, which does work, but I would like to still be able to use beeps in scripts.
How do I disable the "beep on backspace" sound without disabling beeps completely?
