Imagine your tv says in the EULA you can't open it. The only way the TV company knows this and you can get any consequence out of doing it is if you want to activate warranty. In any other scenario they have no clue. You can apply the same thing here. There's no way for Microsoft to know if you reverse engineer a binary in your machine to learn about it, and since you're never gonna send them the binary for repairs, you're good to go.
If nobody finds out about an illegal thing that you did, it doesn't immediately become legal.
Imagine you send a GDPR wipeout request to a company. You have no way to check whether they really delete all your data, but I hope you agree that it would be illegal for them to not do it.
