How to max out Windows forwarder file descriptors limits?

I'm trying to max out Windows forwarder file limits.
When using "max_fd" in limits.conf, I get the following warning:

WARN  TailingProcessor - Constraining max_fd from requested '20000', will use '6667', max_fd constrained to two-thirds of OS fds per process limit (NOFILES), '10000'.  Increase ulimit (ulimit -n) to raise the ceiling on max_fd.

Is there any way to raise the limit above "6667" in Windows? ulimit is of course a Linux feature.

You might want to check this blog out, is not really a number of files like in Linux/*nix instead there's a memory limit for handles
