I am on a Windows Insider hub, and my machine has attempted 3 Win11 updates without my permission on the "Insider" computer - but that's what it is. MS did re-release the System Checker tool to help see if you are "ready" for Windows 11, and does have better results now:

download the appropriate version for your computer. I do not know for certain, but if memory serves correctly, it will not run from Win7. The problem with Win11 is that you need a UEFI "bios", AND a "Trusted Platform Module" (TPM), which is what kills it for ALL of the computers in my house... I do have two computers with UEFI, but they are NOT new enough for a TPM. Supposedly, rumor has it (such a reliable source) that after 1st Jan 2022, that there will be another version of Win11 that will be compatible with older hardware. Don't hold your breath...
