Frequently Asked Questions

Do I need to repurchase Microsoft Office if my PC came with a preinstalled version?

No, preinstalled OEM versions like Office Home and Student are typically linked to your Microsoft account as a digital license during the initial setup. You can reinstall it for free by signing into your Microsoft account.

What should I do if my Microsoft account does not show my Office license?

If the license isn't listed, ensure you are logging in with the exact email used during the first activation. If it still doesn't appear, check your PC manufacturer's recovery tools or use a Windows 11 System Restore point to recover the software.
