> YouTuber Eric Parker demonstrated in a recent video how dangerous it is to connect classic Windows operating systems
The video referenced in that article explicitly connects directly to the internet, using a VPN to bypass any ISP and router protections and most importantly disables any protections WinXP itself has.
So yeah, if you really go out of your way to disable all security protections, you may have a problem.
One comment there points out that XP is old enough for infected attack vectors to have all died out. I dunno.
