If you bought the product online and didn’t get any product key then your Microsoft account will be linked to your Office. You don’t always need a product key to reinstall your Office. However, if you haven’t stored the full product key anywhere then there isn’t a lot that you can do, unfortunately. You can also use these last 5 digits to search your emails in case you got your product key through an email. So, the last 5 digits can help you match the keys with computers. With lots of computers and 100s of product keys, it would be a really difficult task to check which key is used on which computer. The last 5 digits of your product key will be useful if you are an IT guy with lots of computers and licenses. Only 5 digits are stored and these methods mentioned below can be used to extract the 5 last digits of your product key.

Now, you can’t really extract the full product key from your computer because, well, it isn’t stored on your computer. These are the 5 digits that are enough to identify your product key but, as you would have guessed, you will need the other digits to reinstall the Office.

However, with Office 2013, Microsoft doesn’t store the whole product key on your system but rather stores the last 5 digits of your product key. Office 20 stored the full product keys on your computer and there were multiple methods to extract the entire keys. The bad news here is that Microsoft has changed the way it stores product keys with Office 2013. This can be really frustrating considering you can use the product key multiple times (for a limited number of times). You will either have to find the product key or buy a new one if you want to activate/license the new installation. There are many cases where you have to re-install the Windows or you might want to install the application on another computer. The problem is, once the key is lost, you won’t be able to re-install/license the application. However, it’s common to forget or lose these product keys which is understandable considering how many applications we have to install on our computers. All of these applications come with their own unique product key that is required to install and activate the product. In fact, applications like Microsoft Office, Web browsers, Adobe applications and so many more are essential for us. With so many computer applications available in the market, it is normal for us to install various applications on our desktops or laptops.
