Reinstall Office 2013 from Your Microsoft Account
If your copy of Office 2013 was purchased digitally or previously linked to your account, you do not need the physical product key to reinstall it.
Modern Microsoft Office licenses are typically bound to a Microsoft account rather than relying solely on a physical product key. Logging into the account used during the initial setup allows you to redownload the software easily.
Go to the official Microsoft Account website and sign in with the email linked to your Office 2013 purchase.
Navigate to the 'Services & subscriptions' section found at the top navigation bar of the page.
Scroll through your list of owned products and locate 'Office Home and Student 2013'.
Click the 'Install' button next to the product name and follow the on-screen instructions to download and run the installer.

Contact the Service Provider Who Installed Office
If a repair company previously installed Office for you, they might have used a volume license or their own account credentials.

Frequently Asked Questions
Can I extract the Office 2013 product key from my computer's registry?
For Office 2013, Microsoft changed how keys are stored. Only the last five digits of the product key are stored locally on your device, making it impossible to extract the full 25-character key using third-party key finder software.
What happens if I cannot remember my Microsoft account email?
If you forgot the email associated with your Office purchase, try checking your alternate email inboxes for Microsoft purchase receipts. If you still cannot find it, Microsoft Support may not be able to verify your ownership, requiring you to purchase a new version or use an alternative suite.
Is it safe to continue using Office Home and Student 2013?
Because Microsoft ended extended support for Office 2013 in April 2023, the software no longer receives security patches or bug fixes, making it vulnerable to security risks. Upgrading to a newer suite or a free alternative is highly recommended.
