In a prior post, I showed you how to manually configure your computer to enable ExecutionPolicy so you can run Powershell scripts. To make it even better, I now have a powershell script that will create the .REG files you need so all you have to do is run the script and double-click on the file. The script also shows some other pretty cool tricks like opening a dialog box to get a folder path and creating a text file. Simply Copy and paste the following code into PowerShell or PowerShell ISE and watch the magic
