Hi @aforbes HFC Design Service
I’m sorry this happened, especially since the device was deactivated by mistake.
The good news is that this normally does not disable the laptop itself. It only affects the Microsoft 365 apps on that device.
Open Word or Excel and sign in with the same personal Microsoft account linked to your Microsoft 365 subscription. This should reactivate the apps. You can also check your subscription and reinstall Microsoft 365 from the Services & subscriptions page if needed.
If Windows itself no longer allows you to sign in, or you see a specific “device disabled” message, please share the exact message or a screenshot with personal information hidden, as that would be a different issue.
Thank you and please feel free to let me know if you need any further assistance
