I don't know if it's just me but right now I am running three versions of Windows on my hard drive. Win10 and Win7 are much faster when opening things. Win11 is too slow by far. Why? My computer has these parts: CPU:FX6300 MB: M5A78L-M LX V2 GPU: R7 240 2GB 1 HD + 1 SSD PSU: Gamemax GP 650

Basically, Windows 11 uses stronger security features in today's chips and motherboards that older versions of Windows can't handle. On top of that, it needs a TPM chip, which is a hardware spot where Windows stores secure keys for better login and safety checks. It also needs SecureBoot, which uses the UEFI software to make sure the files starting up Windows are genuine. UEFI takes over from MBR and totally changes how computers start and how they store their hard drives (switching from GPT). Windows 11 also needs CPUs...

You shouldn't use that machine for such a big task. It was made for simple things only.

I am confused about why Microsoft makes Windows 11 that hard and basically stops using old computers. Is there a reason for this?

Your FX-6300 is more than ten years old. Even before Win 10 came out, it was normal to have bad performance on low-end computers back then. Win 10 started in 2015. Would you think it would run smoothly on a system that wasn't great in 2005? Actually, the difference between 10 and 11 is usually tiny. Maybe your computer has another problem.

You might be thinking that is correct, but now Microsoft has finally decided to exclude poor old computers from getting Windows 11, just like before.

It's already old. If you got a computer back in 1998, what would you think about running Windows 7 (released in 2009)?

These are the rules for running Windows 10: You need a processor that's at least one gigahertz, or something faster. You also need at least 1 GB of RAM if you're using 32-bit software, but 2 GB if you're using 64-bit software. Your hard drive needs about 16 GB for the old system or 20 GB for the new one. You'll also need a graphics card that supports DirectX 9 or later and a display of 800 by 600 pixels. A dual-core processor made in 2006 is enough to run Windows 10 (which came out in 2015). If Microsoft had done the same thing for Windows 11, it would have been able to run on hardware from 2012

What's the oldest or crappiest Windows 10 setup I've got? Mine is from the early 2009s with a Toshiba Satellite L305-S5955. It has a Celeron processor running at 2.2GHz, 2GB of RAM, and a 250GB hard drive. The only thing I changed was swapping out the original 160GB drive for this bigger one. Right now it's on version 1903 with Build 18362.295. To be clear: "Minimum requirements" just means it starts up, not that it runs smoothly. If you look around the internet, you might see people running Windows 11 even on old computers like this one.

I can say that Windows 11 feels snappy right now, just like Win10 was on a Core 2 processor. Even if you have a dual-core laptop, it works fine for sending emails and doing light office stuff, as long as you have at least 4GB of RAM and an SSD. There is no big delay or lagging that you can feel. It's probably just the drivers or your CPU, which used to be much faster on the C2D because it had 6 cores running at 4.1GHz back when.
