Powershell profiles

Remarks#

Profile file is a powershell script that will run while the powershell console is starting. This way we can have our environment prepared for us each time we start new powershell session.

Typical things we want to do on powershell start are:

importing modules we use often (ActiveDirectory, Exchange, some specific DLL)
logging
changing the prompt
diagnostics

There are several profile files and locations that have different uses and also hierarchy of start-up order:

Host	User	Path	Start order	Variable
All	All	%WINDIR%\System32\WindowsPowerShell\v1.0\profile.ps1	1	$profile.AllUsersAllHosts
All	Current	%USERPROFILE%\Documents\WindowsPowerShell\profile.ps1	3	$profile.CurrentUserAllHosts
Console	All	%WINDIR%\System32\WindowsPowerShell\v1.0\Microsoft.PowerShell_profile.ps1	2	$profile.AllUsersCurrentHost
Console	Current	%USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1	4	$profile.CurrentUserCurrentHost
ISE	All	%WINDIR%\System32\WindowsPowerShell\v1.0\Microsoft.PowerShellISE_profile.ps1	2	$profile.AllUsersCurrentHost
ISE	Current	%USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1	4	$profile.CurrentUserCurrentHost
## Create an basic profile
A PowerShell profile is used to load user defined variables and functions automatically.

PowerShell profiles are not automatically created for users.

To create a PowerShell profile C:>New-Item -ItemType File $profile.

If you are in ISE you can use the built in editor C:>psEdit $profile

An easy way to get started with your personal profile for the current host is to save some text to path stored in the $profile-variable

"#Current host, current user" > $profile

Further modification to the profile can be done using PowerShell ISE, notepad, Visual Studio Code or any other editor.

The $profile-variable returns the current user profile for the current host by default, but you can access the path to the machine-policy (all users) and/or the profile for all hosts (console, ISE, 3rd party) by using it’s properties.
