|On my XP Home the applet file does appear in the location given as well as in the Control Panel. So it seems to me that it is just the icon/file missing in CP.|
You could always uninstall Java 7-9 from Control Panel/Add-Remove progs then download and install it again. However, if you are having no issues it might be best to wait for their next update and see if that happens to fix it. In the meantime you still have a way to change settings.
Note that you should have a copy of javacpl.cpl in c:\windows\system32 which is the exact same version as the one in the Bin folder. If it is missing from System32 you could just copy it over (if it lets you). The control panel files are the ones in System 32.
Always pop back and let us know the outcome - thanks
