Ok, thank you for clarifying.
Also, I found out that the blue colored folder names mean that at some point I zipped or otherwise compressed those folders/files (if the color is green instead, Windows is telling you that the info is encrypted).
I also read one should never delete 'administrator' 'default' or 'all users' folders!
Seems to me that it's perfectly fine though to delete any leftover JAVA folders in 'guest' user account (which I do not use). Java must have installed itself there by default (it's not in all of folders, only some), because I don't remember using the guest account. I may have done so once, for 30 minutes or so. These older JAVA files were NOT removed by JAVARA (I ran it several times) and they also do not show up in Control Panel as a program that I can remove either (only the latest version of JAVA appears in Control Panel). But they are leftover in 'application data' path of some user accounts. Most of the Java folders in there were empty anyway, so it's possible that JAVARA uninstalled them and left behind a small amount of data.
I read someplace that if I had older versions of JAVA in some user account, that if I use that user account, the system cache may put an older version of JAVA into play, thereby creating a security risk.
<<So, does Windows XP create these user folders by default?>>
Yes, see attachment.
That is just how Windows works. Your questiona about Control Panel/Users...relates to user profiles, persons authorized access/use of the system...the accounts are a subset created for each user, with the username (in my case, Louis) identifying each.
