How did BitLocker get activated on my computer?

I'm curious to know, how exactly did BitLocker get activated on your computer? Did you manually enable it through the settings, or was it automatically triggered by some security measure? Perhaps there was a recent update or change in your system's configuration that prompted the activation. It's important to understand the cause so we can ensure your data remains secure and accessible. Can you recall any recent changes or events that might have led to this?
