Execution Policy

While a necessary evil, Execution Policy can sometimes be a pain.

Here's a couple of alternatives to setting the execution policy to Unrestricted:

Powershell.exe –noprofile –executionpolicy bypass –file "C:\Scripts\myScript.ps1"

Get-Content 'C:\Scripts\myScript.ps1' | powershell.exe -noprofile -

(The minus (-) is important!)
