Hello good folks.
Would anyone be so kind and help me with setting or appending a parth variable in Powershell?
Is there an elegant way to do it other than to use some function which edits a registry value? By elegant way I mean some new way in Powershell v5. 
Thank you very much.
Maybe you could use the .NET method SetEnvironmentVariable?
Call it from PowerShell:
[System.Environment]::SetEnvironmentVariable()

Great suggestion,
thank you.
$Env:Path = $Env:Path + ";C:\SomeFolder
I found this solution also, if anybody ever needs it.
