I'm considering purchasing a Windows 7-equipped Dell OptiPlex computer for $50. I love playing old PC games, therefore rather than downloading Windows 10, I want to utilise it as is (Plus the specs of the computer are unimpressive by modern day standards and Windows 10 might not run great). Additionally, I would use it for casual internet browsing and light job tasks (using programmes like Google Docs and Unity). The issue is that despite hearing a lot of individuals claim that using Windows 7 is extremely risky for security, I've also seen a lot of people say that it's okay if you apply common sense. Is it acceptable for me to use Windows 7 in 2022, or should I just upgrade to Windows 10?
