Thanks for the extra details, now it is easier to grasp your problem
The XP on my main PC is real but I only have the licence stuck on the back of the tower so repairing is a no no.
The XP on this oldie is hookey and Micrrosoft is pecking at my copy as we speak.
As a toe-rag on benefits, Mr Gates wants $130 for a genuine licence, that is one weeks money for me and my wife.
Ubuntu is free, it supports firefox and my mail service.
I can't ask for yours and M/S's help if i can't get online.
There, bared my innermost soul.
Take care Guys.
Yes, in this specific case, I would agree that Ubuntu is a good solution for the older machine
