4th gen Intel processors are not supported.

If you have a look at the CPU support for Windows 10. I even created a thread on Twitter showing this: I have a 4th generation i7 in my gaming PC (it's getting on a bit now, but don't do that much gaming on it any way), and to my surprise it was not listed! However I'm still getting updates for this system, and have had no issues what so ever. Then the other night, I was just curious what their supported list for older Intel CPUs looked like for Windows 10. None of my processors were added to this list. Periodically I would check the Intel CPU supported list for Windows 11, but to no avail. Updates are absolutely vital from a security perspective. This immediately put me off since I didn't want to be in a position of not getting updates. Closer to the launch of Windows 11, Microsoft did state that they weren't going to stop anyone install Windows 11 on unsupported hardware, but they weren't going to guarantee updates for these installations. But it turned out that Microsoft only officially support a limited set of CPUs. I did a bit of digging and was even more puzzled since according to the hardware requirements by systems met them all. I was really puzzled as to why (the initial system health check didn't give any information, it just stated that you system was either compatible or not). All came back stating that my systems did not meet all the hardware requirements for Windows 11.

But my excitement soon turned to disappointment when I ran the system compatibility test on my personal laptops using Microsoft's PC Health Check app.

I love new shinny things! So when Windows 11 was announced I was very excited about it.
