Powershell.exe As Elevated?

I am running a command from the run line on the start menu, but when it runs the script, it says:

Warning: To preform some operations you must run an elevated Windows PowerShell console. 

powershell.exe -Version 2 -NoLogo -NoExit -NoProfile -WindowStyle normal -ExecutionPolicy bypass -File C:\script\Run-Update.ps1

In Run-Update.ps1 I have:

import-module pswindowsupdate

get-WUHistory > C:\script\output.txt

Get-WUList >> C:\script\output.txt

How do I run this as elevlated?
