Fix Microsoft Defender Installation Requesting an Experian License
Question details
The user encounters an unexpected Experian license agreement prompt while attempting to install Microsoft Defender.

- Product
- Microsoft Defender
- Device & OS
- not provided
- Scenario
- Installing or setting up Microsoft Defender on a computer.
- Observed behavior
- The installation wizard pauses and asks the user to accept a third-party Experian license agreement, which is not a standard requirement for official Microsoft software.
Before proceeding, do not click 'Accept' or 'Next' on the suspicious Experian license prompt, as doing so may install unwanted third-party adware or software on your computer.
Cancel the suspicious installation and use official sources
Official Microsoft Defender does not require an Experian license. You should immediately cancel this setup and ensure you are downloading from authentic Microsoft channels.
Third-party software download sites often bundle official software with sponsored programs like Experian identity protection or adware. To keep your device secure, you should completely abort the current installation process.
Click 'Cancel' or the 'X' button in the top right corner of the installation prompt to close the setup wizard completely.
Locate the setup file you just downloaded in your 'Downloads' folder, right-click it, and select 'Delete' to move it to the Recycle Bin.
Open your web browser and navigate to the official Microsoft Store or your Microsoft account dashboard to safely download the official Microsoft Defender application.

Check for and remove installed bundled software
If you accidentally clicked 'Accept' or suspect the bundled software has already been installed on your system, you will need to uninstall it manually.
Secure Your Documents with WPS Office
While resolving third-party installer issues on your system, consider switching to WPS Office for a secure, ad-free, and lightweight document editing experience. It is downloaded safely from official sources without the hassle of confusing software bundles.
- 1. Visit the Official Website: Go to the official WPS Office website to ensure a safe and secure download.
- 2. Download the Installer: Click the 'Free Download' button to get the verified setup file.
- 3. Install WPS Office: Run the downloaded installer and follow the straightforward prompts to securely install the software on your device.
