1 year ago that output is coming from the windows batch launcher we ship. Windows doesn't recognize the python file as something to run and "helpfully" treats the bare "ycsb" token as equivalent to having a windows batch file with that name.
unfortunately the current windows batch launcher does not support the argument for additional classpath entries.
Best long term option would be to set up the Windows Subsystem for Linux (WSL) and then use that to run the bash script. We don't have any kind of guidance for doing that though, so you're going to have a bit of groundwork to do.
next best option is to switch to using the python launcher instead of the windows batch launcher. To do that you have to expressly launch python with the ycsb python script as an argument. See the "Verifying things work" section of our wiki page on running on windows from a release.
Last, if you need to stick with the windows batch launcher for some reason you can set additions to the CLASSPATH variable in the setenv.bat file as described in the docs for the windows batch launcher:
@REM Do not set the variables in this script. Instead put them into a script
@REM setenv.sh in YCSB_HOME/bin to keep your customizations separate.
The program seems to be running fine, until it gives us the error "unknown option -cp" YCSB is running on windows computer with python 2.7 installed
