In general, yEd does work on Windows 10. A few users have been experiencing problems when running yEd with Java 10 (see Cannot start yEd 3.18.1 because of java.lang.NoSuchMethodError: <init> for details). This problem can be solved by uninstalling yEd and installing again with embedded Java 8 runtime environment. A corresponding installer is available from the yEd download site.
