I wanted to create an Environment Variable that's stored system-wide.
What I've used in Powershell:
$Env:MyVar = 'Some value'
With gci Env: I can confirm, that the variable has been created successfully.
However it was still missing in the Advanced System Settings in Windows (Win11).
How do I set it up to be visible in that menu?
I found the solution by the time of writing the question. Though simple I still wanted to share this information.
To create a system-wide Environment Variable I used the following code:
[Environment]::SetEnvironmentVariable('MyVariable', 'Some value', 'Machine')
Make sure to start Powershell with elevated privileges (admin) for creating a system-wide variable.
