A 64 bit Java runs quite well on Windows.  The Windows installer stopped
bundling Java with the Windows installer upgrades
<https://www.jenkins.io/blog/2020/08/12/windows-installers-upgrade/> in
Jenkins 2.235.3.  You can read about the Jenkins 2.249.1 testing on Windows
<https://www.jenkins.io/blog/2020/09/12/new-jenkins-release-observations/> in
case you want to read Windows experiences from others.

I don't expect any issues.  I've not seen any reports that were specific to
the transition from 32 bit Java to 64 bit Java.
