On a Windows 10 (64) bit system, perform Java uninstall operation (for example, 8u301/8u311) from "Add or Remove Programs".
JRE/JDK versions get uninstalled successfully. However upon checking the content for default installation directory, in C:\Program Files (x86)\ or C:\Program Files\
observed that the Java\conf directory remains intact. This is frequently reproducible across different systems.
This indicates incomplete uninstall operation.
