What drives me nuts is that even though Windows is the only os I have paid for it's also the only os I use which doesn't include full disk encryption (unless I pay even more). Linux is free and comes with it. Macos is freeish and comes with it. Windows home costs over $100 and doesn't. Those built in ads are also ironic.
Grey market pro keys are like $5 on ebay. I have zero qualms buying them when such a basic and critical form of security is absent from the base edition. Itβs malpractice.
