Method 1 - PowerShell ❤️

   Click the Start Menu, type PowerShell, then open it.

2. Copy and paste the code below, then press enter.

Tip

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 if manually downloading files.
• Be cautious, as some spread malware disguised as MAS by using different URLs in the IRM command.
