This is a main reason why I still use W10 on a MiniPC. When W11 will work well on 8GB, I will reconsider using W11. That Windows works at all is more important than getting security updates.
Microsoft being years too late is better than never... Same for going back to allowing a small start menu etc.
Typical Microsoft finding ways to optimize windows 11 but only rolling it out to low end machines like the rest of us wouldn't like better memory usage or at least the option to have better memory usage.
Microsoft is preparing Windows 11 optimizations designed to improve performance on PCs with 8GB of RAM, targeting high idle memory use. The updates will roll out gradually, with broader improvements expected by the end of 2026.
