Second hand PC says Windows 10 Pro but no key sticker anywhere

Bought a refurbished desktop showing Windows 10 Pro activated. There's no sticker on the case. If I ever reinstall, will it activate again by itself, or do I need to dig the key out now?

Probably nothing wrong. Most machines from the windows 10 era don't have a sticker, the licence is digital and tied to the hardware. Settings, update and security, activation - if it says activated with a digital licence you're fine and a clean reinstall will reactivate on its own. If it says not activated, that's when to worry.
