My main computer is XP, love it, but sadly no support, there is still firefox versions done by volunteers that work well with XP, also Mozilla Thunderbird is supported so can still use it for emails.

I can't get rid of XP since most of my apps only work on XP, I do have an original install disk for it and and install disk for Windows 7, just never installed it, not worth it now though!

I installed XP in a virtual desktop in Win 10 but too many problems trying to get drivers to work, I gave up.
