if this PC OEM, yes, PC manufactured have the best answer
if you still able to boot to windows you can try using any 3rd party software to retrieve it, find reliable software from your search engine
if you buy OS via download, you supposed to be have email confirmation with product key on it
if you buy physical DVD Windows 8.1, you can find it within the box, or if you lost the box, reseller/vendor will help you trace the product key with physical proof of purchase
but if you lost the product key and not able to boot to Windows, I suggest you contact Microsoft activation to change or find the old key
