Powershell – setting the Execution Policy

12 February,2011 by Tom Collins

When you attempt to execute a Powershell script you may see something like the following error message:

 File C:\general.ps1 cannot be loaded because the execution of scripts is di

sabled on this system. Please see "get-help about_signing" for more details.

At line:1 char:14

+ ./general.ps1 <<<<  -inputfile "create_sql2008.sql"

    + CategoryInfo          : NotSpecified: (:) [], PSSecurityException

    + FullyQualifiedErrorId : RuntimeException

 This means the Execution Policy is not set with appropriate permissions.

 The Execution Policy defines the level of restriction on Powershell script execution.

The 4 levels possible are:

All Signed   - (Script must be signed by a trusted publisher)

Remote Signed  - (Scripts downloaded scripts must be signed by a trusted publisher)

Unrestricted – (All scripts can be run)

Restricted – (Can’t run any any scripts.Interactive mode)

 To check your current level use Get-ExecutionPolicy :

 PS> Get-ExecutionPolicy
All signed




To change your policy use Set-ExecutionPolicy such as. Be careful which Policy you choose :

 Set-ExecutionPolicy  RemoteSigned
