While administering a single node Cassandra on Windows, I noticed that the stop-server.bat script returns before the cassandra process has actually terminated. For use cases like creating a script "shut down & create backup of data directory without having to worry about open files, then restart", it would be good to make stop-server.bat wait for Cassandra to terminate.
All that is needed for that is to change in apache-cassandra-3.11.3\bin\stop-server.bat "start /B powershell /file ..." to "start /WAIT /B powershell /file ..." (additional /WAIT parameter).
Does this sound reasonable?
