Go with humility first, you screwed up. Follow it up with a joke about how you discovered a flaw in the configuration of work laptops, and now they can fix it to prevent someone else from being able to do that 🤷♂️
I think you'll be ok
Thanks, I thought of something even better. Slap Linux on that thing! Wipe the whole drive on "accident". Linux is way more innocuous than pirate Windows 🤷♂️
