Everyone please stay on-topic.
v2.1.1.7917 is from May 2021. Which is not too old, but update anyway for bug fixes. Some users believe older Windows releases don't get as much benefit from newer NTLite changes. There's no functional need to update.
But consider if everyone replying to your questions is running a later version, do they want to spend time on something that could have been fixed months or years ago?
