Windows SYSTEM input - not implemented yet

I’m using the v1.3 nightly build: http://52.216.226.91/dl.influxdata.com/telegraf/nightlies/telegraf-nightly_windows_amd64.zip

My goal is to get the uptime from the system input; however, the following error shows in the log file. Is there a different input for collecting this on Windows? This is what I use for Linux.
