Pls I need a help on a payload for "whoami" And "systeminfo" command

[kali-man-lab]

I found a windows server suffering from bluekeep vulnerability on a bug bounty program, but I can't write a detailed poc on the vulnerability using This script because it doesn't have any payload to run commands on the target... And I don't have an idea to generate one(metasploit module is not an option). Pls your help will be appreciated 🙏. Just 2 simple commands payload for steps to reproduce .Your twitter account is not reachable
