It sounded like a good thing, to be honest, but it seems that there is a catch. The catch is that if your PC is considered as being unsupported, like having an incompatible CPU or a computer that only has TPM 1.2 instead of TPM 2.0, it means that it will not be able to receive Windows 11 updates.
You’ll still be able to use the operating system if it manages to install on your computer, but you can pretty much forget about receiving updates via the Windows Updates. While you might be fine not receiving updates for new features and whatnot, keep in mind that these updates also contain bug and security patches that are critical, so you could be essentially leaving yourself unprotected.
That being said, perhaps allowing Windows 11 on unsupported devices could be a way for users to test if Windows 11 is worth upgrading their PC for, but either way it’s something you’ll want to keep in mind if your current build does not officially support the upgrade.
