There are various "fixes" to allow setup on older machines, but I would not recommend those unless you fully understand what running it on an unsupported processor means. Does it mean you may not use features you are hoping to get or does it mean standard day2day processes will run slower or even faulty? Please inform yourself before considering these "fixes". Unfortunately, I have not come across a complete explanation myself. If someone has a document on "why not install win11 on my CPU", please add it here.
