I\'m attached to the nice blue colour of the PowerShell window when you launch it from one of the pre-installed shortcuts. However, if you manually launch powershell.exe, yo
Here's a really easy way:
Start -> run "sysdm.cpl" -> advanced -> Environment Variables
Scroll Down through system variables, double click PATHEXT
Add .LNK; as depicted below:

Copy-Item "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell\Windows PowerShell.lnk" "C:\Windows\System32\powershell.lnk"
You can further customize the .lnk in C:\Windows\System32 to your liking.
Please note that this will only work because you have added the .lnk to the list of acceptable extensions AND c:\windows\system32 is the first item in the search path (PATH system variable) by default.
This will not customize the console if it is launched via cmd.exe.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\PowerShellHere\command]
@="C:\\WINDOWS\\system32\\cmd.exe /c start powershell -NoExit \"cd '%1';(get-host).ui.rawui.windowtitle = 'Oompa Loompa'\""
[HKEY_CLASSES_ROOT\Directory\shell\PowerShellHere\command]
@="C:\\WINDOWS\\system32\\cmd.exe /c start powershell -NoExit \"cd '%1';(get-host).ui.rawui.windowtitle = 'Oompa Loompa'\""
I am using cmd.exe to call "start" which will launch the powershell.lnk and pass the current working directory as an argument. Doesn't seem to work from the address bar yet. I should have gone home 45mins ago, but your problem was fun to solve! :)
Bonus Points: You can thread the commands sent to Powershell. So, if you are looking to modify the Powershell console's title attribute:
\"cd '%1';(get-host).ui.rawui.windowtitle = 'Oompa Loompa'"
Simply add a semicolon between commands.
Happy shelling
