I agree. I've been running Windows 11 for months on an i5 3317U CPU, 12 GB RAM. NO TPM. NO TPM2. And yet my computer runs smooth as butter. I'm posting with it now. Windows 11 is very nice. The "tricks" are minimal, if they can even be called tricks at all. There really isn't much to it. Well worth doing the upgrade.
So, that was an upgrade with or without using a bootable USB drive per post 19? (The former of which would mean reinstalling all app software, backing up and reloading all data (should be backed up anyway), etc.?
One of the not-so-minor pains of clean installs as upgrades is having to make sure one has saved things like spell check dictionaries, having to reset various app settings and customizations, etc. :-(
