KB ID 0001417 Problem If you’ve arrived here, you are trying to run a script, and you cant; PS C:\Users\{User-name}> .\{script-name}.ps1 .\{script-name} : File C:\Users\{User-name}\{script-name} 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. At line:1 char:1 + .\{script-name} + ~~~~~~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess PS C:\Users\\{User-name}>   Solution  Execute the following command; Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass Then run your script. THIS WILL ONLY WORK: While that PowerShell window is open, so don’t close it if you are running a lot of scripts. I Want to Always be Able to Run Scripts? OK you can either change the ‘Scope’ of that last command, from ‘Process’ to to ‘CurrentUser’, or ‘CurrentMachine’. Process: The execution policy affects only the current Windows PowerShell process. CurrentUser: The execution policy affects only the current user. LocalMachine: The execution policy affects all users of the computer. Or you can simply change the policy ‘Globally’; Set-ExecutionPolicy {Value} Possible values are; Restricted: Does not load configuration files or run scripts. Restricted is the default execution policy. AllSigned: Requires that all scripts and configuration files be signed by a trusted publisher, including scripts that you write on the local computer. RemoteSigned: Requires that all scripts and configuration files downloaded from the Internet be signed by a trusted publisher. Unrestricted: Loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs. Bypass: Nothing is blocked and there are no warnings or prompts. Undefined: Removes the currently assigned execution policy from the current scope. This parameter will not remove an execution policy that is set in a Group Policy scope.
