Regarding Windows 11, I haven't upgraded yet, but I've heard mixed reviews. Some people love it, while others have had issues with compatibility and performance. It's always a risk when upgrading to a new operating system. Personally, I'm sticking with Windows 10 for now, but I'm curious to see how it develops. On a side note, I recently got a cheap Windows 10 key from an online marketplace and it worked like a charm. It's worth looking into if you need to activate your Windows or just want to save some money.
