How to find your Windows 10 product key

Being able to locate your Windows 10 product key at a moment’s notice is important. Recovering after a system wipe, building a new PC for fun or just replacing a broken one — you never know when you’ll need to reinstall your copy of Windows. And since the product key is needed to utilize all of Windows 10’s features as well as receive crucial updates, placing it in a secure location for later use is wise.  

If you do happen to misplace your Windows 10 product key, don’t worry. The physical key isn’t actually needed thanks to a Command Prompt; with a few clicks here and there, you’ll be able to pull up the missing key on your PC. Take a look at our guide below as it explains the step-by-step process.

Note that the following instructions are for people who either purchased a physical copy of Windows 10 or bought the digital version through an authorized reseller. If you purchased a digital copy via the Microsoft Store, then Windows 10 is connected to your Microsoft account. All you’d have to do is log into Microsoft after reinstalling Windows 10 to get back up to speed. If you bought a computer with Windows 10 already installed, like a Microsoft Surface, the product key is baked into the firmware and cannot be pulled up.

Even if your PC dies you won’t have to worry because Windows 10 can run without the product key, just not a full capacity. All you’d have to do is install Windows 10 again, use the Command Prompt to find the key and then verify it online.
