Я не думаю, что вы можете улучшить существующий процесс. Но я нашел способ в PowerShell 5 запустить мой скрипт в новом повышенном процессе. Надеюсь, это поможет
# Get the ID and security principal of the current user account
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);
# Get the security principal for the administrator role
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;
# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole))
{
# We are running as an administrator, so change the title and background colour to indicate this
$Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
$Host.UI.RawUI.BackgroundColor = "DarkBlue";
Clear-Host;
}
else
{
# We are not running as an administrator, so relaunch as administrator
# Create a new process object that starts PowerShell
$newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";
# Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
$newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
# Indicate that the process should be elevated
$newProcess.Verb = "runas";
# Start the new process
[System.Diagnostics.Process]::Start($newProcess);
# Exit from the current, unelevated, process
Exit;
