Hi Percy
Windows are ending support only, but the O/S will continue to work fine.

In my view, Windows XP was one of the best, if not the best operating system Microsoft ever produced.

Your A/V security systems seem to be looking after you OK. They should still provide periodic updates for new threats.

Bottom line: If it's doing everything you need, stay with it if you like.

(Be aware also that Windows 8 has a big learning curve)

Kind regards
