Windows 11 running stable from its launch on my 11 year old Acer Aspire 8943g laptop with Intel gen 1 core i7-720QM processor.

I am currently using windows 11 on my dual core laptop and it's running smoothly which was lagging with windows 10 previously. Just I have bypassed the tpm requirements with original windows 11 ISO file.

The main security feature that involves hardware capabilities is called TPM. Trusted Platform Module can be provided via a hardware module that attaches to TPM pins on a motherboard or via CPU.
Windows uses TPM for "...services like BitLocker drive encryption , Windows Hello, and others, to securely create and store cryptographic keys, and to confirm that the operating system and firmware on your device are what they're supposed to be, and haven't been tampered with."

However, TPM 2.0 (current standard) isn't bulletproof. There have been multiple exploits discovered in recent years that allow attackers to bypass security provided by TPM.

Windows 11 adoption must be so low according to Microsoft's expectations that they must come up with tricks to shove it in your face and force you to update. Wouldn't be surprised to hear of more "oopsies" within the year.
