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

To change values in the Machine or User scopes, you must use the methods of the System.Environment class. To make changes to Machine-scoped variables, you must also have permission. If you try to change a value without sufficient permission, the command fails and PowerShell displays an error.

The reason why this isn't working is because SetEnvironmentVariable defaults to the process scoped env vars so this is the same as doing $env:PATH = "new value". You can call the overload where you set the Machine scoped vars but see my above comment as to why you don't use to use that. Also as mentioned by u/BlackV entries in the C:\Program Files\WindowsApps folder should not be on the PATH directly. These entries are installed per user which then adds an App Execution Alias in %LOCALAPPDATA%\Microsoft\WindowsApps which is in the user's `PATH` scoped envvar. You should be ensuring that winget is installed for that user and provisioned as part of the default user profile so new user profiles will get it by default. More on reddit.com

April 15, 2024env and environment variables in Powershell
$env is a powershell object just like $true. If you want to set an environment variable there's 2 normal ways to do it, one using $env, the second using [Environment]::SetEnvironmentVariable Using $env will only set the variable for the current powershell process, whereas using [Environment]::SetEnvironmentVariable you can set it for different areas (process, user, or machine). When you do $INCLUDE you're not setting an environment variable, you're just creating a variable called $INCLUDE. see http://technet.microsoft.com/en-us/library/ff730964.aspx More on reddit.com

This is what I came up with after hours of debugging (as I was using PowerShell for the very first time). # Test folder $InstallLocation = "C:\bin" # To add folder to PATH $persistedPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine) -split ';' if ($persistedPath -notc

If you'd like the variable to be more permanent, you should add it to your .bashrc, .bash_profile, or similar so it gets exported every time you start a new shell session. Here's some Microsoft documentation about managing environment variables on Windows, if that's the environment you are using.

April 15, 2024 -
Hi all,
We've got an odd issue where random machines (all Win11) cannot run Winget, even though it's installed. I've identified the cause as being Winget isn't included in the PATH environment variable. Now I've got a script written for this (as an Intune Remediation), but in testing this won't stick.
Found an article about setting this to the Machine context, but not sure if I'm doing it right because it still won't goddamned stick. Script below - can anyone assist with this?
# Get winget path into variable
$wingetPath = Resolve-Path "C:\Program Files\WindowsApps\Microsoft.DesktopAppInstaller_*_x64__8wekyb3d8bbwe"
# Extract PATH into separate values
$pathParts = $env:PATH -split ';'
# Append winget path to PATH values
$addToPath = $pathParts + $wingetPath | Where-Object { $_ }
# Reconstitute and set PATH with new variables
$newEnvPath = $addToPath -join ';'
[System.Environment]::SetEnvironmentVariable('PATH',$newEnvPath)
