Warn of missing SSE4.2 and refuse update

[Richard-L]

Correct me if I'm wrong but I read that Win11 24H2 requires a CPU supporting SSE4.2. If the update is still installed, the system would just fail to boot.

Is this correct?

I have Win11 23H1 on a CPU with only SSE4.1. I wanted to be extra sure that forcing the new version onto the system would work, and then stopped when I read about this.

If it's all true, then I would suggest a Flyby feature to inform the user of this stuff, and refuse the update.

Nvm if it already does.
