Assistance needed in analyzing malware

Attached is a malware masquerading as a game download and I need help analyzing it. I am curious what excatly it does do and does it leave something running on the computer after a reboot.

I have done some analysis and found out that decrypts file data\CW9iIgkpzugL.Q3 and executes it using powershell.
