While I personally am not one to worry about things like this, it does seem somewhat ironic that people will trust a random person on the internet enough to download a file from them that modifies a core component their OS, to allow it to have security updates... hmm. Along with that, many are doing it avoid using an OS that they don't trust. I have a feeling that the percentage of users that can 100% verify without a doubt that this user made patch is safe is incredibly small, the rest are simply putting their trust in a small group of people they don't know to avoid putting their trust in a larger group of people they don't know.
That said, this was inevitable and if for some reason I was in the situation of having to use Windows 7 (for compatibility reasons) on a brand new CPU I'd certainly do it if the general consensus was that it was safe. Disabling security updates for Windows 7 due to hardware differences is absurd and Microsoft should know better, even with all the mistakes they make.
