Well if you really want to you can get the output handle from the PEB[0]. You can then call NtWriteFile[1] using syscall `0x0008` (Windows 10 x64 only)[2].

I completely forgot stdout handle is in the PEB! Thanks! After learning how the windows x64 syscall calling convention works I got it working on win10.
