Integration tests fail on Windows #39904
Description
The latest master cannot run integration tests on windows due to:
Exception in thread "main" java.nio.file.AccessDeniedException: C:\Windows\elasticsearch
at sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:83)
at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:97)

It looks like the temporary folder is not set which causes the default/system folder (C:\Windows) to be used instead which obviously fails.
From try-outs it looks commit 465343f introduced this change in behavior.
