Powershell Basics for Dummies - Set-ExecutionPolicy

Set-ExecutionPolicy

• By Default Microsoft has disabled scripting  in an effort to prevent malicious code from executing in a PowerShell environment. 
• You should use Set-ExecutionPolicy command to control the level of security surrounding PowerShell scripts. 

Four levels of security exist:

• 1. Restricted — Restricted is the default execution policy and locks PowerShell down, so that commands can be entered only interactively. PowerShell scripts are not allowed to run.
• 2. All Signed — If the execution policy is set to All Signed then scripts will be allowed to run, but only if they are signed by a trusted publisher like Microsft etc.
• 3.Remote Signed — If the execution policy is set to Remote Signed, any PowerShell scripts that have been locally created will be allowed to run. Scripts created remotely are allowed to run only if they are signed by a trusted publisher like Microsoft.
• 4. Unrestricted — Unrestricted removes all restrictions from the execution policy.

You can set an execution policy by entering the Set-ExecutionPolicy command followed by the name of the policy. For example, if you wanted to allow scripts to run in an All Signed manner you could type:

Set-ExecutionPolicy All Signed
