Execution Policy

What it is

Execution policy is a safety gate for scripts—not a full security boundary. It mainly reduces accidental runs of downloaded scripts.

Check the policy

Scopes stack; the effective policy is what matters day to day.

Get-ExecutionPolicy -List

Common learning approach

On a personal learning machine, many people set the CurrentUser scope to RemoteSigned.

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

Bypass carefully

You can bypass for one process when needed, but prefer fixing the policy or unblocking trusted files intentionally.

powershell -ExecutionPolicy Bypass -File .\hello.ps1
