About the Windows 7 support expiration.

I am a total computer illiterate. I'm still on XP. Keep getting messages from sites saying I need to upgrade my browser. NOT GOING TO HAPPEN.
When this computer stops doing what I need it to do, it goes in the garbage, and I am back to "snail mail", and paper checks. I have allready stopped using plastic for 80 % of buying. Using "coin of the realm". Tired of all the "tracking"
So, if I disappear from this site, you know what happened.
