You are correct. If third party applications rely on the FHE encrypted data, then they will need to change the way they quire it. But if it's companies sensitive internal data stored outside (e.g. in a cloud) and the company ist the only one that calculates on it, then it may be worth looking into that.
As of 2018 I didn't see (maybe I've missed some) any commercial implementation of FHE, but that might have been changed by now, since it's a rapidly growing wide supported subject.
I didn't use Windows at all, everything ran on Linux.

ok.

I don't know about Windows but I assume, Linux would be similar?

we don't do that. Also, we have third party applications. In case they need to be modified, this is impossible.

right, but only if it makes sense. To put a wallet in the file system and its key right next to it does not make sense but only serves to make IT heads and security "gurus" go quiet. In these cases, only replacing them by competent ones helps.
