Resolving PowerShell Execution Issue Due to Execution Policy
PowerShell scripts often fail to execute due to the system's execution policy. The execution policy is a safety feature that controls the conditions under which PowerShell loads configuration files and runs scripts. Here's how you can resolve this issue:
Sample Error Message: running scripts is disabled on this system. For more information, see about_Execution_Policies at https://go.microsoft.com/fwlink/?LinkID=135170.
Check Current Execution Policy
First, check your current execution policy. Open PowerShell and run the following command:
Get-ExecutionPolicy
Change Execution Policy
If the returned policy is Restricted, PowerShell prevents scripts from running. To change this, you can set the
policy to Unrestricted, RemoteSigned, or Bypass.
Unrestricted: This policy allows all scripts to run.
Set-ExecutionPolicy Unrestricted
RemoteSigned: This policy allows scripts downloaded from the internet to run if they are signed by a trusted publisher.
Set-ExecutionPolicy RemoteSigned
Bypass: This policy allows all scripts to run, regardless of where they come from and whether they are signed.
Set-ExecutionPolicy Bypass
Changing the execution policy might expose your system to risks. Understand the implications of each policy before changing it.
Run Script with Policy Change
If you don't want to change the system-wide policy, you can run your script with a temporary policy change:
powershell -ExecutionPolicy Bypass -File script.ps1
This command runs script.ps1 with the Bypass policy, regardless of the system's execution policy.
Execution Policy Scope (Recommended)
You can also change the execution policy for a particular scope (CurrentUser, LocalMachine, etc.):
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
This command changes the execution policy for the current user only.
Remember to always run PowerShell as an administrator when changing the execution policy.
