Question details
The user needs to reinstall Microsoft Office 2021 and fix file associations after performing a Windows reset on an HP laptop.

- Product
- Microsoft Office 2021
- Device & OS
- Windows
- Scenario
- Recovering applications and file access after completing a system reset on the Windows operating system.
- Observed behavior
- Office 2021 is either removed or its default application associations are cleared, causing document files to appear unavailable or open with the wrong program.
Ensure you have access to the Microsoft account used to purchase Office 2021, or have your original product key ready before starting the reinstallation process.
Reinstall Office 2021 and Set Default Apps
Download the Office installer from your Microsoft account and reconfigure Windows settings to open your documents with the correct Office applications.
A Windows reset removes installed desktop programs, including Microsoft Office. After reinstalling, Windows might not automatically recognize Office as the default handler for your files, requiring manual adjustment in the system settings.
Sign in to your Microsoft account at office.com, navigate to Services & subscriptions, locate your Office 2021 purchase, and click Install to download the setup file.
Open the downloaded setup file and follow the on-screen instructions to complete the installation of Word, Excel, and PowerPoint on your HP laptop.
Click the Start menu and select Settings (the gear icon), then click on Apps from the left sidebar.
Navigate to Default apps, scroll down to 'Choose default apps by file type', and assign Word for .docx, Excel for .xlsx, and PowerPoint for .pptx files.

Frequently Asked Questions
Why do my Office files open in the browser after a Windows reset?
Resetting Windows can clear your default app settings. When this happens, Windows defaults to opening web-compatible files in Microsoft Edge. You can fix this by going to Settings > Apps > Default apps and selecting the corresponding Office application.
Will resetting my HP laptop delete my Office 2021 license?
A Windows reset removes the installed software files, but your Office 2021 license remains safely tied to your Microsoft account. You simply need to download the installer and log in to activate it again.
How do I find my Office 2021 product key if I lost it?
If you purchased Office 2021 digitally, the license is linked to your Microsoft account. Log in to the Services & subscriptions page on the Microsoft website to view your product and install it without needing the 25-character key.
