Fix for PowerShell Script cannot be loaded because running scripts is disabled on this system error

Problem:
On trying to run a PowerShell script from the PowerShell console, received this error message: “File C:\temp\GenerateRpt.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.”

This is due to PowerShell’s policy to prevent untrusted scripts which can affect your Server environment.

Solution for “cannot be loaded because running scripts is disabled on this system“:

• Open PowerShell Console by selecting “Run as Administrator” and set the execution Policy with the command: Set-ExecutionPolicy RemoteSigned
• Type “Y” when prompted to proceed 

This in fact sets the registry key: HKLM\Software\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell
Policy parameter takes below values:

1. Restricted – No scripting allowed
2. Unrestricted – You can any scripting
   • No signing required
3. Remote signed – good for Test, Dev environments
   • Only files from internet need to be signed
   • This is the default setting
4. All signed  – local, remote script, it should be signed.
   • user must agree to run script
