Like they all say, it is about money and the hand in hand monopoly the Tech Industry has with Big Cooperate OS makers. Proprietary Gear, OS's and all that is HUGE BUSINESS. There are way around the install, although you are 'on your own'. I have an AIO Dell, XPS One 2710 I plan on installing 11 on. it has a i7-3770S CPU @ 3.10GHz, 3101 Mhz, 4 Core(s), 8 Logical Processor(s) and meets the other minimum requirements for the most part. Just have to enable TPM or bypass it in my Reg.
I can just make a backup then change the settings so 11 Will install. I still have my 10 DVD, Number and I can always reinstall if it goes bad. But the point is MONEY and GREED. They can make any software work on any System, Memory, Processor Speed and HD Speed are your bigger concerns. Otherwise simple slow system. I have Ubuntu PC's that are OLD systems, as in 10 and 15 years old that run as fast/faster than Windows at times, LOL. All I did was add better video cards and more memory.
