It has been a while I last worked with PowerShell. I had my custom profile where I had my own prompt and some other customizations. Now I cannot find it anymore. I’ll start with the new one and I am saving it on my blog, so it will be easier to find in future:

Function Prompt {
  $PromptData="PS $($executionContext.SessionState.Path.CurrentLocation)$('>' * ($nestedPromptLevel + 1)) "
  $host.ui.RawUI.WindowTitle=$PromptData +'-'+(Get-Date).tostring()
  # .Link
  # http://go.microsoft.com/fwlink/?LinkID=225750
  # .ExternalHelp System.Management.Automation.dll-help.xml
}

The prompt function comes from the scripting guy blog. To customize your profile, just open it in a text editor (in my case: code)
