Office 2010 include applications such as Word, Excel, PowerPoint, and Outlook. They’re available as a one-time purchase for use on a single PC.
Most software programs require a product key as part of the installation process, including all recent versions of Microsoft Office. If you've lost your Microsoft Office product key, you'll need to find it before you can reinstall the software suite. Here will show you two methods to find your Microsoft Office product key from your computer after installation. Even if you forgot or lost the activation key.
Office 365 plans include premium versions of these applications plus other services that are enabled over the Internet, including online storage with OneDrive and Skype minutes for home use. With Office 365 you get the full, installed Office experience on PCs, Macs, tablets (including iPad® and Android™ tablet) and phones. Office 365 plans are available as a monthly or annual subscription. Learn more.
See system requirements for compatible versions of Windows and macOS, and for other feature requirements.
You don’t need to be connected to the Internet to use Office applications, such as Word, Excel, and PowerPoint, because the applications are fully installed on your computer.
However, Internet access is required to install and activate all the latest releases of Office suites and all Office 365 subscription plans. For Office 365 plans, Internet access is also needed to manage your subscription account, for example to install Office on other PCs or to change billing options. Internet access is also required to access documents stored on OneDrive, unless you install the OneDrive desktop app.

You should also connect to the Internet regularly to keep your version of Office up to date and benefit from automatic upgrades. If you don’t connect to the Internet at least every 31 days, your applications will go into reduced functionality mode, which means that you can view or print your documents but cannot edit the documents or create new ones. To reactivate your Office applications, reconnect to the Internet.
Yes. Documents that you have created belong fully to you. You can choose to store them online on OneDrive or locally on your PC or Mac.
If you cancel your subscription or it expires, you can still access and download all your files by signing in to OneDrive directly using the Microsoft account you used to set up Office 365. You do lose the additional storage that comes with your subscription, so you must save your files elsewhere or buy more OneDrive storage if your OneDrive account exceeds the free storage quota.
If you purchase an auto-renew subscription, your subscription starts when you complete your purchase. You can purchase auto-renew subscriptions from Office365.com, MicrosoftStore.com, iTunes®, and some other retailers. If you purchase a pre-paid subscription, your subscription starts when you activate your subscription and land on your My Account page. You can purchase pre-paid subscriptions from a retailer or reseller, or a Microsoft support agent.
If you have an active Office 365 Home subscription, you can share it with up to four members of your household. Each household member you share your subscription with can use any of your available installs on their PCs, Macs, iPads, Android tablets, Windows tablets, iPhones® or Android phones, get an additional 1 TB of OneDrive storage, and manage their own installs from www.office.com/myaccount.
To add someone to your subscription, visit www.office.com/myaccount and follow the onscreen instructions to add a user. Each person you add will receive an email with the steps they need to follow. Once they have accepted and completed the steps, their information, including the installs they are using, will appear on your My Account page. You can stop sharing your subscription with someone or remove a device they are using at www.office.com/myaccount.
“The cloud” is a friendly way of describing web-based computing services that are hosted outside of your home or organization. When you use cloud-based services, your IT infrastructure resides off your property (off-premises), and is maintained by a third party (hosted), instead of residing on a server at your home or business (on-premises) that you maintain. With Office 365, for example, information storage, computation, and software are located and managed remotely on servers owned by Microsoft. Many services you use every day are a part of the cloud—everything from web-based email to mobile banking and online photo storage. Because this infrastructure is located online or “in the cloud,” you can access it virtually anywhere, from a PC, tablet, smartphone, or other device with an Internet connection.
Most software programs require a product key as part of the installation process, including all recent versions of Microsoft Office. If you've lost your Microsoft Office product key, you'll need to find it before you can reinstall the software suite.
Microsoft Office product keys are encrypted inside the Windows Registry, so searching for them manually is nearly impossible. You'll find a string of numbers once you locate the correct registry key, but what you'll find is encrypted text, not a working Office product key you can enter.
Fortunately, programs called key finders do the finding and decrypting for you, giving you your valid, paid-for Office product key — that missing puzzle piece so you can successfully reinstall the program.
If you don't find your key while using one of the methods outlined below, the only legal option you have left is to buy a brand new copy of MS Office. As often as you may come across free product keys for Office, or key generator programs, neither are good ways to go about this.
Microsoft Office 2019 & 2016 & 2013
The Microsoft Office 2019, 2016, and 2013 product key situation is unique compared to older versions of Office (below).
Unfortunately for us, only the last five characters of the 25-character Office 2019, Office 2016, or Office 2013 product key is stored on your computer, making a product key finder pretty much useless in this case.
I know, right away I'm going back on some of the stuff I said above! For whatever reason, Microsoft completely changed how they handled product keys with these newer versions of MS Office
Of course, this unfortunate fact doesn't change the reality that you still need that product key to reinstall either version.
If you have an installed version of Microsoft Office 2019, 2016, or 2013 via your Office 365 subscription, you don't need to worry about product keys. Just sign in to your account and download and install the latest version of Office to your computer.
It's not all bad news that key finder programs are no longer helpful with these versions of Office. In fact, the new way that Microsoft is handling Office keys might not be such a bad thing after all.
Microsoft Office 2010 & 2007
Like all versions of Office, Microsoft Office 2010 and Microsoft Office 2007 both require a unique product key during the installation process.
If you're sure that you no longer have the physical product key for your version of Microsoft Office, or you've lost or deleted the email receipt that included the product key in it, you might, as you read in the introduction above, be able to extract the key from the registry using a key finder tool.
LicenseCrawler, the key finder program we recommend for Office 2010 & 2007 product keys in that tutorial, will find your product key in just seconds.
Older Versions of Microsoft Office
Older versions of Microsoft Office, like Office 2003 (2003), Office XP (2001), Office 2000 (1999), and Office 97 (1996) all also require product keys during installation.
Considering how old some of these versions of Microsoft Office are, it'd be surprising if anyone still has the product key around.
The Office 2010/2007 tutorial above could be used for any of these versions of Office as well, but we've found that Keyfinder Thing, the key finder tool we recommend in this tutorial, does a better job with these older suites.
