It also serves as a nice buffer when you are switching jobs - you can take the PTO and still be employed (& so covered by health insurance for a bit longer, and stocks are still vesting), making for a nice break from work.

Discretionary <> unlimited, so the answer to your question most likely will be: "my manager".

Edit: props to Microsoft for not being scared to call the policy by its true name.
