Cannot use double quotes inside command
When I try to run more complex commands (e.g .\GodPotato.exe -cmd "cmd /c net localgroup "Remote Desktop Users"" the command fails.
With your command, it assumes you are ending at the second double quote. So
.\GodPotato.exe -cmd "cmd /c net localgroup "
Most programs you can use single quotes in addition to double quotes. In this case you will also have to escape the double quotes
.\GodPotato-NET4.exe -cmd 'cmd /c net localgroup \"Remote Desktop Users\"'
cmd /c didn't like using the single quotes around Remote Desktop Users
If you chose to use powershell -c instead of cmd /c this would also work:
.\GodPotato-NET4.exe -cmd "powershell.exe -c net localgroup 'Remote Desktop Users'"
Also for future reference, I don't think you exactly need the cmd /c this command worked just fine for me:
.\GodPotato-NET4.exe -cmd 'net localgroup \"Remote Desktop Users\"'
Hopefully that helps
