In a home context, probably none if you don't care about it, but in a business environment, especially if you are a big consumer of MS products, the activation is meaningless. The check your licences not your activations.
They are. In fact no home consumer should be buying an OEM licence for themselves

I didn't mention a business environment. Of course in a business environment it matters.
It's like the use of photoshop. You can pretty much guarantee that all teenagers/young adults that use it on their own home PCs, are using a cracked copy.
I use a cracked copy, not because I 'don't want to pay' but becuase there's no way I could afford to pay. There's a lot of software I use that haven't purchased, like some CAD packages and rendering engines. Not because I don't want to support the devs or I'm trying to get something for free.
It's because I can't afford the asking price, and I'm not using them for professional purposes.
I work in a CAD office, so any CAD work I do that makes money is done on systems that have licenses for the software I use, while at home, I use cracked software to basically improve my skills and usage of these applications.
I use cracked rendering software to practice producing 3D imagery so I can put it forward to my work place as a potential software for them to use and purchase licenses for.
Now, if I were to go freelance and be self employed, then I would purchase the software. My view on it is that morally it's not a problem unless you're making money out of said software.
I'm pretty sure adobe takes that view too. They don't care about the kids and teenagers using cracked copies of their software. They're bothered about the so called professionals like design studios, that are making money from work that needs photoshop.
Which is the way it should be really.
I couldn't buy some of the expensive software I use without actually knowing how to use it anyway, but I feel that it's good that I do use it because I am making people aware of the software that otherwise wouldn't be.
Fryrender is an example, yes I'm using a cracked copy at home to practise gettings to grips with the software. There's a demo, but it's far to restrictive to show what actual usability is like.
So I'm using a cracked copy to pracise with. With the intention of arguing a case for the software at work as a project of mine is to evaluate the software that we use and present a suitable rendering package to improve the quality of the work that we do.
Which I would class as the home environment anyway.
But personally, I wouldn't use software for finiancal gain if I didn't have the license to use it.
