I doubt very much that Brave is still releasing for Windows 7. Frankly if they are, they should be ashamed of themselves. Windows 7 should NEVER be used for web activities, even with Brave as the browser.
That said, I'll ping the WindowsPingList folks for you, but really, at least get a copy of Win10, and reserve your Win7 for strictly offline activities.
Here's my take.
1. Let's face it; Windows XP and 7 were, and are, the best operating systems Microsoft put out. They were stable and easy to use. They also gave the user control over their PC's, instead of the other way around with MicroThief now having control via Windows 8, 10, 11 and soon to be 12.
Yes, W7 no longers get any kind of support from M/T, but W7 is still the easiest O/S to use bar none. And there are still companies that make internet security software for it.
So if someone has said software, and they as long as they aren't on sites that indulge in porn, gambling and other high risk activities, I think it can be relatively safe. I still use W7 for certain online activities, such as FR for instance.
2. Many users, like myself, still have older hardware that we use on a daily basis which can only support W7 and 10 (and Linux of course). My PC's are Intel Generation 1 and G5/6. My G5/6 can run W10 efficiently enough, but the G1 system cannot though I use a scaled down install of W10 on each of them (all my systems are dual boot). In many cases, I find it easier to use W7. I think others feel the same way, and many are not tech savy to the point where they can use a Linux O/S.
Now factor in Windows 11 and soon, 12. There's no way our old hardware can, or will, be able to handle either of them. What are we to do?
There are no easy answers, but if we can use even older versions of browsers like Brave, then that's what we have to go with.
