You wouldn't be able to use it regardless, it's more a matter of how difficult it would be to get back to usable. Basically, my presumption is no operating system at the low end. If they weren't going to do that, they wouldn't have said unusable is my thought on it. They would have said removing company content.

Now, if you never connect to the internet again, you'd never know. But you'll find out what it is once you do. Basically, at a minimum you'd have to reinstall windows, likely with a new copy, in my opinion.
