Vista - how to set system's environment variable permanently

How to add a Windows envirenment var permanently with PowerShell?

The PowerShell Cookbook by Lee Holmes says this:

$oldPersonalPath = [Environment]::GetEnvironmentVariable("PATH",
"USER")
$oldPersonalPath += ";d:\tools"
[Environment]::SetEnvironmentVariable("Path", $oldPersonalPath,
"User")

however, when i do

[Environment]::GetEnvironmentVariable("Path", "User")

nothing is returned. Piping it to get-member returns the error: Get-
Member : No object has been specified to get-member.

I can do the following but it's just per session.

$envath = $envath + ";C:\Users\xah\PowerShell scripts\"

A quick search in this group doesn't seems to find answer.

Thanks.

Read this article and especially note the caveat regarding restarting PowerShell.

To set it PERMANENTLY you use SetEnvironmentVariable, but to have it
take effect NOW you need to use the Env: drive.

Write yourself a little script that does both...

Thanks.
apparantly my problem was the wrong variable. There's no “Path� env
var of User category on my machine.

I now try:

[Environment]::GetEnvironmentVariable("Path", "system")

but that's a error. Apparantly the name is not “system�. What should i
put for the second param? It's not clear to me where i'd find this
info. Am still grobing Windows system and docs...

Read the error message in its entirety. Doesn't it tell you what the valid
values are for that second argument?

Were you able to get to the text of this article?
