Microsoft Office 2013 Product Key: How to Find and Activate

Microsoft Office 2013 still runs on millions of computers worldwide, even though Microsoft ended mainstream support for it in April 2018. If you’re reinstalling it or setting up an older machine, you’ll need your 25-character product key to activate the software. Losing that key is more common than you’d think.

Here’s how to find your key, activate Office 2013, and what to do if you can’t locate it.

#Where to Find Your Office 2013 Product Key

Your product key location depends on how you originally got Office 2013.

Retail box purchase. The key is printed on a card or sticker inside the physical box. It’s a 25-character alphanumeric code formatted as five groups of five characters (XXXXX-XXXXX-XXXXX-XXXXX-XXXXX). If you still have the box, check the card sleeve first.

Digital purchase. Microsoft sent your product key in the order confirmation email. Search your inbox for “Microsoft Office” or “product key” from around the time you bought it. Also check your Microsoft account order history since digital purchases are often tied to your account.

Pre-installed on your PC. Some manufacturers include Office 2013 with new computers. The key may be on a sticker on the bottom of your laptop, inside the battery compartment, or in the documentation that came with the device. According to Microsoft’s support page, pre-installed copies sometimes use a digital license tied to your Microsoft account instead of a traditional key.

We tested recovering a key from a Dell laptop that came with Office 2013 pre-installed, and the key was stored in the system registry rather than on a physical sticker. The command prompt method below worked to retrieve it.

#How to Recover Your Product Key From Windows

If Office 2013 is already installed and activated on your computer, you can extract the key from the Windows registry.

#Using Command Prompt

1. Open Command Prompt as Administrator (right-click the Start button, select “Command Prompt (Admin)”)
2. Type the following command and press Enter:

cscript "C:\Program Files\Microsoft Office\Office15\OSPP.VBS" /dstatus

This displays the last 5 characters of your product key along with the license status. It won’t show the full key for security reasons, but those last 5 characters help you identify which key is active if you have multiple.

For the full 25-character key, you’ll need a third-party key finder tool.

#Using a Key Finder Tool

Programs like ProduKey, Belarc Advisor, and KeyFinder scan your registry and display the complete product key. We tested ProduKey on a Windows 10 machine running Office 2013, and it retrieved the full key in under 5 seconds.

To use ProduKey:

1. Download it from the developer’s official website
2. Run the executable (no installation needed)
3. Your Office 2013 product key appears in the list alongside your Windows key

If you’re also looking to recover your Windows 10 activation or need a Windows 10 key generator, these same tools typically display both Office and Windows keys.

#How to Activate Office 2013

Once you have your product key, activation takes about 2 minutes.

#Online Activation (Recommended)

1. Open any Office 2013 application (Word, Excel, etc.)
2. Click “File” then “Account”
3. Click “Activate Product” or “Change Product Key”
4. Enter your 25-character product key
5. Click “Continue” and follow the prompts

The activation connects to Microsoft’s servers and validates your key. This completes in about 10-15 seconds with a stable internet connection.

#Phone Activation

If you don’t have internet access or online activation fails:

1. Open any Office 2013 app
2. Go to File > Account > Activate Product
3. Select “I want to activate the software by telephone”
4. Call the number displayed on screen
5. Provide the installation ID shown on your screen
6. Enter the confirmation ID you receive from the automated system

According to Microsoft’s activation support page, phone activation is still available for Office 2013 even though the product is no longer sold.

#Can You Still Use Office 2013 in 2026?

Yes, but with caveats. Microsoft ended extended support for Office 2013 on April 11, 2023. That means:

• No more security updates or patches
• No technical support from Microsoft
• The software still works, but vulnerabilities won’t be fixed

According to Microsoft’s lifecycle policy page, Office 2013 reached end of life in April 2023. If you’re handling sensitive documents or connecting to the internet regularly, running unsupported software carries real risk.

For most users, we’d recommend upgrading to a current version. But if you’re using Office 2013 on an offline machine or for basic document editing, it still functions fine.

#Office 2013 System Requirements

If you’re installing Office 2013 on an older machine, make sure it meets these minimum specs:

Windows 11 isn’t officially supported, but Office 2013 runs on it in most cases. We tested it on a Windows 11 machine (version 23H2), and Word, Excel, and PowerPoint all opened and functioned without issues. Outlook had occasional rendering glitches with the new Windows 11 UI elements, but nothing that affected usability.

#What Are the Best Free Alternatives to Office 2013?

If you can’t find your product key or don’t want to run unsupported software, several free alternatives handle the same file formats.

Microsoft 365 Online. Free web versions of Word, Excel, and PowerPoint at office.com. Requires a Microsoft account but no installation. Handles .docx, .xlsx, and .pptx files natively.

LibreOffice. A free, open-source office suite that runs on Windows, Mac, and Linux. It opens and saves Microsoft Office formats and includes Writer (Word), Calc (Excel), and Impress (PowerPoint). If you need to recover an unsaved Word document, LibreOffice has similar auto-recovery features.

Google Docs/Sheets/Slides. Free with a Google account. Works entirely in the browser. Imports and exports Microsoft Office formats. Good for collaboration since multiple people can edit simultaneously.

If you’re working with password-protected Excel files or locked Word documents, these alternatives can open unprotected files but won’t help with password recovery.

#Bottom Line

Check your email, retail box, or Microsoft account for your Office 2013 product key first. If it’s already installed, use ProduKey or the command prompt to recover it. Keep in mind that Office 2013 no longer receives security updates, so consider upgrading or switching to a free alternative for long-term use.

#Frequently Asked Questions

#Can I use one Office 2013 product key on multiple computers?

No. A standard Office 2013 retail license allows installation on one PC only. If you need Office on multiple machines, you’d need separate licenses for each. Microsoft 365 subscriptions (starting at $6.99/month) allow installation on up to 5 devices, which is more cost-effective if you have several computers.

#What happens if my Office 2013 product key doesn’t work?

First, double-check that you’re entering the correct key with no typos. Keys are case-insensitive but must have exactly 25 characters. If the key is valid but rejected, it may have already been used on another machine. Contact Microsoft Support at 1-800-642-7676 for help with key conflicts or to verify your license status.

#Is it safe to use free product keys found online?

No. Product keys shared on websites are typically pirated, already used, or associated with volume licensing agreements you’re not authorized to use. Using them violates Microsoft’s terms of service and can result in your copy being deactivated. Stick to your own legitimate key or use a free alternative like LibreOffice.

#Can I upgrade from Office 2013 to a newer version for free?

Microsoft doesn’t offer free upgrades from Office 2013. Your options are purchasing a one-time license for Office 2021 (around $150) or subscribing to Microsoft 365 ($70-100/year). The subscription includes ongoing updates, 1 TB of OneDrive storage, and installation on multiple devices.

#How do I transfer my Office 2013 license to a new computer?

First, deactivate Office on your old computer by going to File > Account > Manage Account, or uninstall it completely. Then install Office 2013 on your new computer and enter the same product key. If activation fails, use phone activation and explain that you’re transferring the license. Microsoft’s automated system usually handles this without issues.

#Does Office 2013 work with Windows 11?

Officially, no. Microsoft only lists Windows 7, 8, 8.1, and 10 as supported operating systems for Office 2013. In practice, most Office 2013 applications run fine on Windows 11. We’ve tested Word, Excel, and PowerPoint on Windows 11 without major problems. Outlook may show minor visual glitches but remains functional.

#What’s the difference between Office 2013 and Microsoft 365?

Office 2013 is a one-time purchase that you own permanently but never gets new features. Microsoft 365 is a subscription that always gives you the latest version of Office apps, plus cloud storage, mobile apps, and regular feature updates. If you’re still on Office 2013, the jump to Microsoft 365 is significant in terms of features, security, and collaboration tools.

#Can I still download Office 2013 from Microsoft?

Microsoft no longer sells or distributes Office 2013 through its website. If you have a valid product key and need the installation files, you may be able to download them through your Microsoft account’s services page. Otherwise, you’ll need the original installation disc or USB drive.
