Hi i have seen other (locked) post about this with no official answer.
is there any known issue running es or kibana on windows server 2019?
(its not on support matix)
thanks
I think all you can do is wait for the support matric to be updated before trying to install.

If you try to install you may run into some odd issues that is not worth fighting until the support matrix shows direct support for win2019.
