If sometime during a PowerShell session you need to see or to temporarily modify the PATH environment variable, you can type one of these commands:
Copy$env:Path # shows the actual content
$env:Path = 'C:\foo;' + $env:Path # attach to the beginning
$env:Path += ';C:\foo' # attach to the end

Changing the actual environment variables can be done by
using the env: namespace / drive information. For example, this
code will update the path environment variable:
Copy$env:PATH = "SomeRandomPath"; (replaces existing path)
$env:PATH += ";SomeRandomPath" (appends to existing path)
Making change permanent
There are ways to make environment settings permanent, but if you are only using them from PowerShell, it's probably a lot better to use Powershell profiles script.
Everytime a new instance of Powershell starts, it look for specific script files (named profile files) and execute them if they do exist. You can edit one of these profile to customize your enviroment.
To know where those profile scripts are located in your computer type:
Copy$profile
$profile.AllUsersAllHosts
$profile.AllUsersCurrentHost
$profile.CurrentUserAllHosts
$profile.CurrentUserCurrentHost
You can edit one of them, for example, by typing:
Copynotepad $profile

For more information on profiles, see about_Profiles. On Windows, you can specify a scope for the SetEnvironmentVariable() method as the third parameter to set the environment variable in that scope.

February 3, 2022Script to set environment variable for specific process.
Theoretically yes you can but practically it's not a simple thing to do. The simplest option is to create a shortcut that calls a ps1 or bat file which sets the env var before calling your exe. The exe will inherit anything from the parent environment block. Edit: I forgot to mention it's probably too late to set it after the process has started, OpenSSL is most likely being initialised before you could inject the new env var. Creating a shim to set it before starting Titanfall would be your only viable option. More on reddit.com

September 20, 2023Please help me understand the purpose of environments in PowerShell
Powershell has no "Environments". If they " look similar to variables", you're most likely talking about environment variables. They are not related to Powershell, they are part of the environment the OS provides to process. They provide information to the processes. Partly they are maintained by the OS itself, partly they are user maintained to configure and control processes. More on reddit.com

PowerShell Environment Variables
August 25, 2025 - If the variable is set only in the current session using “$env:”, it will not persist after closing PowerShell. Make sure you are setting the variable at the user or system level using System.Environment class or registry editor. Environment variable names are case-insensitive on Windows, but you might encounter case-sensitivity issues when working with cross-platform scripts such as in PowerShell Core on Linux or macOS.

I need to set a system wide environment variable and I need it to be persistent.
Every time I try setting it with PowerShell it seems to only be good for that PowerShell session.
Is there a way to do this with PowerShell?

You can use the setx command. The other choice is to modify the following registry key:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment by adding the variable name as a value. This will guarantee a persistent change.

Running the powershell.exe executable to start a new session, using the ExecutionPolicy command line parameter to set a policy for the session. The PSModulePath environment variable contains the path that PowerShell searches for modules if you do not specify a full path. It is formed much like the standard PATH environment variable, with individual directory paths separated by a semicolon.

Environment variables in PowerShell | Opensource.com
Environment variables can be set, recalled, and cleared with some of the same syntax used for normal variables. Like other variables, anything you set during a session only applies to that particular session. If you want to make permanent changes to a variable, you must change them in Windows Registry on Windows, or in a shell configuration file (such as ~/.bashrc) on Linux or Mac. If you’re not familiar with using variables in PowerShell, read my variables in PowerShell article before continuing.
