Ah you see now it's not "just internet browsing".
Linux is excellent and can give older computers a new lease of life but as I have said the learning curve is very steep initially especially when it comes to installing software. You can get all the equivalent softwares for linux that you can get for Windows but again getting them to work with what the rest of the world is using, Windows, can be a nightmare.
I would think you should be okay with Windows Home. I cannot see any reason to go with a higher version. I have installed Windows 10 32 bit on a much older laptop that only has 2 gig of RAM. It's not ideal but it does work and it browses the internet as well as my much much newer Windows 10 machines. You will, of course, have to buy Windows 10 and if your computer is really really old then it may be more cost effective to go for a new computer. You can run Windows software from Linux using software like Wine but, again, the learning curve is quite steep.
The fact that you say you"migrated" from Windows XP makes me think that that was your last OS and that is a shame because if your computer had had Windows 7 then you could get a Win 10 upgrade for free. You can get a free download from here:-

But you will need a valid product key from Windows 7 , 8 or 8.1. This is an ISO and you can make either a bootable USB key or a bootable DVD using this tool but, as I have said, unless you have a valid product key for Win 7, 8 or 8.1 then this toll will not work.
Bottom line really to all of this is that you do need to be thinking about a brand spanking new computer with a brand spanking new Windows 10 on it and as much RAM as you can afford.
