| function remove-environment {
param (
[string][ValidateNotNullOrEmpty()]$name,
[switch]$perm,
[switch]$machine
)
$value = ""
if (-not $perm) {Remove-Item -Path env:\$($name) -Force}
else {
if ($machine){$type = "Machine"}
else {$type = "User"}
[System.Environment]::SetEnvironmentVariable($name, $value, $type)
}
} |
If you want to remove it permanently use the –perm switch otherwise it is just removed from the session
