Diffucult to say then without checking your specifications against the windows 11 requirements list.

It’s bit confusing, you may be able to force an update (not reccomended) as windows update may not be ready to give it to your particualr machine spec yet.
I wouldn’t rush to upgrade or worry though, by the time win10 no longer gets updates, you’ll be wanting a new machine anyway, possibly, presumably.
And you’re really not missing much, win11 looks a bit more modern and some stuff has been moved about/removed for no particular reason that’s obvious to me, it doesn’t actually function any better or worse from what I can tell.
I’ve upgraded my laptop out of curiosity, but I’ll be leaving my main PC on win10 for the forseable future… i.e until my hand is forced when they eventualy stop doing security updates for windows 10.
