PowerShell Profile

This is basically the profile posts from http://www.snowland.se (which is written as different posts by Rikard Rönnkvist) and simply put together in a single profile script which I use on all of my Windows boxes:

 # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
 # Profile script (very heavily) based on the example here:
 # http://www.snowland.se/2010/02/23/nice-powershell-prompt/
 # by Rikard Ronnkvist (www.snowland.se)
 #
 #
 # Script includes a multicolored prompt with marker for sessions started as Admin and marker for providers not filesystem:
 # C:\Windows\System32>
 # [Admin] C:\Windows\System32>
 # [Registry] HKLM:\SOFTWARE\Microsoft\Windows>
 # [Admin] [Registry] HKLM:\SOFTWARE\Microsoft\Windows>
 #
 #
 # Additions made to add command history (stored in the user's profile as \Documents\WindowsPowerShell\commandHistory.xml)
 # http://www.snowland.se/2013/06/14/auto-load-command-history/
 # also by Rikard Ronnkvist (www.snowland.se)
