Create and customize your PowerShell Profile

You can create a PowerShell profile to customize your environment and to add persistent elements to every PowerShell session that you open. Think of profiles as a logon script for PowerShell that lets you tweak your experience and have it persist every time you open a new window. The automatic variable $PROFILE contains the path to the profile for the Current User and Current Host profile script.

Now run the Get-ExecutionPolicy command:

As you probably see, the policy is configured to Restricted. The Execution Policy must be adjusted with the following command:

Press A follow with Enter to change the Execution Policy.

Check if you PowerShell Profile exist

If you have never opened your profile before, it won’t yet exist. To check for an existing profile use Test-Path.

If it comes back with False, then create your profile using New-Item.

If you want to create a profile for all users, just run the following command:

Example PowerShell Profile

Below a basic profile example that tweaks the prompt, adds an alias, and a custom function. It also show you a welcome message, date and time and set the location to C:\.

Save your profile and close PowerShell and open it again.
