Ya, it is normal to see that, you got a lot of crap functions for just a Chat software(QQ), IME(input method editors), as they want to suck your money so badly.
It is all right if the software is optimize enough, and allow me to disable the crap functions to reduce the CPU/memory usage, but most of them are not and even pop a window to telling you use this, use that functions, which is the issues...

Even worst, some of them will silent install other software that they bundle into it, or their other software too, then their installed crap software will keep silent install other software, and you know what happen....

Anyways, you can try disable Intel services, I disable all of them so far, and don't see any issues at all.

It look like most of them are just for logging(IRST), playing protected video(Graphic), and maybe provide advanced feature for managing computer(ME/MEI).
And even you don't wanna disable it, they did a good jobs for keeping the CPU and mem usage very low too, just too bad they often drop their 2-4 years old Product, so you can't get newest driver that should be working great for newest Windows, until you buy their new products....
