Note

The irm command in PowerShell downloads a script from a specified URL, and the iex command executes it.
Always double-check the URL before executing the command and verify the source is trustworthy when manually downloading files.
Be cautious of third parties spreading malware disguised as MAS by altering the URL in the PowerShell command.
