Reload environment variables inside powershell window

Question

In my Powershell script I'm setting machine-level environment variables with:

[Environment]::SetEnvironmentVariable("MY_VARIABLE", "MY_VALUE", "Machine")

Inside this same script, I am calling another application that will look for the variable above. Is there a way for me to reload the current session with the variables I created above?

No but you can also set the environment variables for the current process i.e. $env:MY_VARIABLE = 'MY_VALUE'. Any application you start should inherit the environment variables set in this fashion.

This should be done manually, and to avoid mistype when load Environment variable value to the current session you could try:

Write-Host $Env:MY_VARIABLE   # should be empty
$Env:MY_VARIABLE = [Environment]::GetEnvironmentVariable("MY_VARIABLE", "User")
Write-Host $Env:MY_VARIABLE`  # should be updated
