I have an HP Spectre X360 that is going on 7 years old with an Intel(R) Core(TM) i7-6560U CPU. I was able to install Windows 11 through their Windows Insider Program and it has been running flawlessly. The Windows 11 version is 22H2, OS Build: 22623.1325. Microsoft actually provided periodic updates for the version of Windows 11 that I have on my laptop. I also have a newer HP Envy X360 with a much new generation Intel I7-1165G7 processor. The Windows 11 version is 21H2, OS build: 2200.1574. I have noticed some minor differences in the graphic interface between the two but that's about it. The speed difference between the older and the new laptop is negligible. The only reason I initially got the new laptop was because the SSD on the older laptop stopped working. Once I got the new laptop, I decided to get a new SSD for the old laptop and to see if there was some way of installing Windows 11 after I initially installed the original Windows 10 that was on it before the SSD failed. In retrospect, I didn't need to buy a new laptop after all. As a matter of fact, I am writing this response on my older laptop. It has a 15 inch screen whereas my new laptop only has a 13 inch screen. The 15 inch screen is much easier on these 73 year old eyes.
