From Wikipedia: "By using the CPUID opcode, software can determine processor type and the presence of features..."

What exactly Marvin's Utility does? After I install updates/software Marvin's utility checks if CPUIDs of new installs/updates is the same as it is was before installation or corresponds to the ones that are held within Marvin's utility and if it different, utility replace them? So Marvin's utility already have info about my CPU and I have to run it AFTER I install updates/software? (and what if after updates Leo prompts me to restart computer I can't tell him wait a moment I need to run Marvin's utility so on restart I can patch you ? )

Is that so?

Sorry for being dumb
