I uninstalled Java Runtime Environment 6 through Add/Remove Programs - with the intention of reinstalling the latest update version which I have not yet done. I did a Search for Java and found several files - some as far back as 1999...got my pc in 2002. Before I reinstall JRE, can all these files be deleted? some are .dll, Windows $NT Service Pack Uninstall, Windows help, Java Scripts Kapersky, etc. Thanks for any suggestions.
