Powershell takes too long to close; can't totally override the default prompt function

Question

I don't know what's happening with my Powershell. I have a shell registry key that allows me to open a Powershell window in a directory. The content is:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Unrestricted -NoExit 

And this is my custom defined prompt function:

function prompt {
    Write-Host ("on ") -NoNewLine -ForegroundColor White
    Write-Host ("$env:COMPUTERNAME") -NoNewLine -ForegroundColor Gray
    Write-Host (" in ") -NoNewLine -ForegroundColor White
    Write-Host ($(Get-Location)) -ForegroundColor Gray
    Write-Host ("$") -NoNewLine -ForegroundColor Magenta

    return "> ";
}

It should return something like

on PC-NAME in C:\\

$>

However, it returns this:

on PC-NAME in C:\\

$> PS C:>

Anything wrong at all with my Powershell? How do I get more debug information to help you guys?

Answer 1

I could fix this issue by commenting out a few functions in the PSReadline module that was installed. The module would add a `b to the end of the current prompt, append the user prompt to it, and would restore the default prompt when Powershell was being closed.
