How to Reset Windows Without Losing Your OEM Office License
Question details
The user wants to reset their Windows PC but needs to ensure their OEM or preinstalled Microsoft Office license is not lost during the process.
- Product
- Microsoft Office
- Device & OS
- Windows
- Scenario
- Performing a Windows factory reset or clean installation while retaining preinstalled software licenses.
- Observed behavior
- Resetting Windows removes installed applications and local activation data, potentially causing the loss of the OEM Office license if not properly backed up or digitally linked.
Do not proceed with the Windows reset until you have verified your Microsoft account credentials and confirmed that your OEM Office license is digitally linked to your account.
Link Your OEM License to a Microsoft Account and Reactivate
The safest way to retain an OEM license is to ensure it is digitally linked to your Microsoft account before resetting the PC.
Modern OEM licenses are usually digital and tied to your Microsoft account rather than a physical key. By verifying this link before resetting, you can easily restore your software.
Open any Office app like Word. Click on 'File' > 'Account'. Under 'Product Information', verify which Microsoft account email is associated with your active license.
If your OEM PC came with a physical card or digital receipt containing a 25-character product key, write it down and keep it in a safe place.
Proceed with resetting your Windows PC by navigating to Settings > System > Recovery > Reset this PC.
After the reset is complete, open your web browser, navigate to www.office.com, log in with your linked Microsoft account, and download your Office version to reinstall and activate it automatically.
Contact Microsoft Support for Activation Assistance
If you are unable to activate Office after the reset despite having a valid OEM license, Microsoft Support can assist with manual reactivation.
Switch to WPS Office for a Hassle-Free Experience
If you lost your OEM Office license after a Windows reset and do not want to repurchase it, WPS Office is a fantastic, lightweight, and free alternative. It offers high compatibility with major office formats without complex activation procedures.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for Windows.

- 3. Open Your Files: Launch WPS Office and directly open your existing Microsoft Word, Excel, or PowerPoint files with complete format retention.
Frequently Asked Questions
Can I transfer my OEM Office license to a new computer?
No, OEM (Original Equipment Manufacturer) licenses are strictly tied to the first computer they are installed on and cannot be transferred to a new PC or a newly replaced motherboard.
Where can I find my preinstalled Office product key?
For modern preinstalled Office versions, the product key is usually injected into the PC's motherboard firmware or digitally linked to the first Microsoft account used to activate it. You often will not find a physical 25-character key.
What if I forgot the Microsoft account used for my OEM Office?
If you forgot the account, try checking all your email addresses for confirmation emails from Microsoft. If you still cannot locate it, you will need to contact Microsoft Support with your device's original proof of purchase.
