Moved here as I think you are running Linux Mint as a guest on a Windows host? I'd expect you'd configure the virtualized resources on the host OS, or have you installed something on Linux Mint to be able to do that? Looking up how Hyper-V handles virtualized CPUs, I think you have some reading to do as you're not understanding how Hyper-V does this: http://www.altaro.com/hyper-v/hyper-v-v ... explained/
As for your search problem, please just use your preferred Internet search engine. Add the search term "site:linuxmint.com" to limit search results to the Linux Mint websites. All major search engines support that. That way you can also use the advanced options your search engine gives you for limiting your search results further.
For example, search for "cpu settings site:linuxmint.com" on Google or DuckDuckGo.
But as explained, you won't find relevant result with that as you're going about this the wrong way. Configure Hyper-V. if you need help with that, probably there is some Hyper-V users' forum?
