"gamecopyworld is a solution, not the solution."
Cannot agree more, and it is a feasible solution for some.
"Using Security Essentials is downright stupid if you're on Windows 10"
This is your personal opinion, in reality it has proven its threat defending capabilities and they are still growing with every iteration of Windows 10. It is at least one of the few solutions where Microsoft won't compromise you to uninstall it in case of an support incident, let it be a private use or small business.
"Being an MCP doesn't mean swat really. Don't insinuate it brings any weight to what you recommend."
just a way to show I am not just a John Doe average user out there. Each of us forumer here may have plenty or few expierence in the field, this is one way to prove it. I fell into this MS drug in 1986 so can kindly expect I have done a whole lot. Though I never had the time to promote to MSCE or higher.
"Installing cracks is a major security issue"
this can be true. It depends on your system health, firewall and security awareness. It is not like I recommended it without taking any measures, Eric
"gamecopyworld is a great vehicles to test out zero days"
I doubt that one will recode a crack for a random old game just to use zero days. I admit timestamps of files can be manipulated easy, there was even a DOS tool for this.
"Dual booting is more secure, at least if you just refuse to use most if not all of your credentials on that copy of Windows and use a local account or a separate Microsoft account for the purpose of playing these games and encrypt your other disk part with BitLocker and refuse to give this copy of Windows the recovery key."
Thats the truth but at the end it is cumbersome as I've said. Setting up a dualboot and force to load an unsigned driver is like telling a noob how to flash lineage on Android to update ones devices.
"Don't complain here you weren't warned."
I have warned too, but not in your manner: "Like you are at risk for sure and a bad boy if you do".
"It's a lot of hassle for every single game you play and I usually still need to reach for the CD to install the game (again)."
I would like to disagree, I prefer ISOs or Alcohol images if there was no other way to get the stuff off my owned medias.
