am a complete blockhead re computers. please will someone explain in simple language what the java application does, do I need it and can I uninstall the progamme and updates? many thanks and sorry to be so dumb -will have other questions later!
Java updates itself quite often but when it does it installs a new version but doesn't remove the old version.
I think the current version is version10 but check in add remove programs and if you have several different versions installed you can safely remove all but the newest version.
