Exe File That Adds Himself to Startup (PowerShell Injection)

Well, I'm new to hacking.

I created, with SET and Kali, a powershell injection batch file and now I need help to convert the bat file to an exe.

I want to make that exe file copying himself to a hidden folder somewhere in the computer and add that copy to the Windows Startup folder. (I know this is possible using python. I just need some help).

Thank you btw
