If you see this error: .\DeepBlue.ps1 : File .\DeepBlue.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170.
You must run Set-ExecutionPolicy as Administrator, here is an example (this will warn every time you run a ps1 script):
Set-ExecutionPolicy RemoteSigned
This command will bypass Set-Execution entirely: Set-ExecutionPolicy Bypass
See get-help Set-ExecutionPolicy for more options.
Please note that "Set-ExecutionPolicy is not a security control" (quoting @Ben0xA)
