Heh - well ... if you ask me I'll always say a full node running on linux

nothing for win for a temp use. I am very illiterate in Linux and currently can't set aside Linux comp.
I have been using bitcoin core on windows for most of a year. I guess it is time for me to migrate that to linux. That said, having the full block chain on your own computer helps prevent hacking as well as the health of bitcoin since you are another copy for the system to compare off. The main reason for not using windows is all the viruses that can intercept what goes between your hands and the internet (Kano, can you confirm). Keep your firewalls, virus scanners and other security measures in place (including safe browsing and not opening unknown emails) and it will help for the short term. When you can swing the money and time, probably best to migrate it to linux (which I will be doing now too).
linux it is but will take me awhile...
I'd suggest a ubuntu base linux - they're easy to install but also easy to upgrade.
The LTS (Long Term Support) versions last a few years, and some time before the end of that LTS you simply have to upgrade it - which is just a few commands and wait and watch

Edit: any yes the reason to avoid Windows is indeed all the viruses and key loggers out there.
The anitivirus software that everyone uses doesn't stop all viruses, it only stops 'known viruses' by pattern matching ... and that is by design by McAffee in the beginning.
He designed it that way so that you'd have to always get data/version updates regularly from them.
Permanent source of income ...
Windows (all versions at least since Windows 7) log your key strokes (and lots of other stuff) so that Microsoft can see them if needed.
Yes this is a well known fact, not an urban legend - it started with the Beta of Windows 10 and then they back ported it to the older windows versions via updates.
You just gotta hope no one ever manages to get at that log on your computer ...
