Dual booting to windows 7, tips?

I don’t plan to make this my main OS whatsoever as its EOL and windows 10 has more support,
but I’d like to relive some old memories, and I read the survival guide and ill definitely go after it but I do wonder, any other tips?

I’m tech savvy so I know I’ll sound stupid but is there community software updates that people like me could use?
personally, I might completely uninstall the browser of windows 7 and just transfer files from windows 10 to 7, and is wifi a big risk? I’ll start installing now, hopefully I get answers shortly, pls give advice
