When you try to run a PowerShell script that has not been signed by a trusted publisher, you may get the following security error: This security error can occur when the PowerShell's execution policy is set to Allsigned or Remotesigned and the script isn't signed. Allsigned execution policy allows execution of all Powershell scripts that are signed. Before executing the script you will be prompted to confirm that you trust the publisher that has signed the script. Remote execution policy restricts the execution of downloaded scripts that are unsigned. Scripts that are executed from the local computer doesn't have to be signed. SolutionThere are different methods to overcome this error. You may choose to either sign the PowerShell script, change the execution policy, bypass the policy or unblock the file so that it can run once on that session. Check Execution PolicyFirst of all check your execution policy using the cmdlet Get-ExecutionPolicy PS C:\> Get-ExecutionPolicy AllSignedThe list parameter in Get-ExecutionPolicy cmdlet tells you the execution policy for each scope. PS C:\> Get-ExecutionPolicy -list Scope ExecutionPolicy ----- --------------- MachinePolicy Undefined UserPolicy Undefined Process Undefined CurrentUser Undefined LocalMachine RemoteSignedThe default execution policy for all windows version except for Windows 2012 R2 is Restricted. The default execution policy in Windows 2012 R2 is RemoteSigned. Changing Execution Policy PermanentlyThe easiest but unsecure method of getting rid of this error message is to change the ExecutionPolicy using the SetExecutionPolicy cmdlet. The following command sets the execution policy to unrestricted. PS C:\> Set-ExecutionPolicy unrestrictedPress Y to confirm the change when prompted. The policy change is updated in the registry and will remain until you change it again. Changing Execution Policy TemporarilyInstead of changing the execution policy permanently you could set a different policy for a single PowerShell session. This is done using the ExecutionPolicy parameter of powershell.exe Open a command prompt or PowerShell and run the command: C:\> powershell.exe -executionpolicy -bypassThe above command opens a PowerShell session with execution policy for that session set to Bypass which means nothing is blocked. Unblocking a File that was downloadedWhen the execution policy is RemoteSigned, the files that are downloaded from the internet (or from emails) are blocked to protect your running unsafe scripts. If you trust the contents of the script are safe then you can unblock it to run on your session using the Unblock-File cmdlet PS C:\> Unblock-File -Path C:\Downloads\script1.ps1Once you have changed the Execution policy permanently or temporarily for a session or a particular script you can continue to run the script but before you do that make sure the contents of the script does not harm your computer

If you have tried to run a PowerShell script that isn’t signed, you’ve likely stumbled upon the following error <PowerShell Script file> is not digitally signed. You cannot run this script on the current system. Windows PowerShell is a shell initially developed by Microsoft for the purposes of task automation and configuration management. There’s no wonder that its Execution Policy is set to Restricted, which protects from running malicious scripts. However, this security error can occur when the PowerShell Execution Policy is set to AllSigned or RemoteSigned and the script isn’t signed. If you’d like to sign the script and solve this, here are a few methods that may help. What can I do if PowerShell is not digitally signed?1. Check and change Execution PolicyLet’s take a look at how to check the Execution Policy, as well as how this can be used to get rid of your error. First of all, you may run Get-ExecutionPolicy cmdlet to get your Execution Policy. The list parameter in the Get-ExecutionPolicy cmdlet tells you the policy for each scope. At this point, a convenient method is to change the Execution Policy using the SetExecutionPolicy cmdlet. The following command sets the execution policy to Unrestricted: PS C:> Set-ExecutionPolicy unrestricted. Press Y to confirm the change when prompted. The policy change is updated in the registry and remains this way, at least until you change it again. Note that Unrestricted means loading absolutely all configuration files and running all scripts. If you run an unsigned script that was downloaded from the Internet, you are though prompted for permission before it runs. 2. Bypass the current PowerShell sessionAnother quick fix is to run Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass. This simple command above will set the execution policy to bypass the current PowerShell session. Even better, once you close this PowerShell session, these settings will be lost. 3. Unblock the file that was downloadedWhen the Execution Policy is RemoteSigned, this requires that all scripts and configuration files downloaded from the Internet or from emails are signed by a trusted publisher. If you trust the contents of the script are safe, then you can unblock it to run on your session using the Unblock-File cmdlet: PS C:> Unblock-File -Path C:Downloadsscript1.ps1.
