Question details
Users need a way to prevent Windows 10 from automatically reverting their chosen default PDF application back to Microsoft Edge.
- Product
- Windows 10
- Device & OS
- Windows 10
- Scenario
- Opening and managing PDF files on a Windows 10 system after setting a customized third-party PDF reader.
- Observed behavior
- Windows 10 frequently overrides the user's customized default PDF viewer preference, changing the file association back to Microsoft Edge after system restarts or updates.
Ensure that your preferred PDF reader (such as WPS Office or Adobe Acrobat) is fully installed, updated, and functioning correctly on your Windows 10 computer before adjusting system settings.
Reassociate PDF Files via Windows Default Apps Settings
The most effective method to set and maintain your default PDF viewer is by changing the file type association directly within the core Windows 10 settings.
Windows 10 manages file associations in a centralized Settings menu. By explicitly telling the operating system to open .pdf files with a specific application, you can override Microsoft Edge's default behavior.
Click the Start button in the bottom-left corner of your screen, then click the gear icon to open the Settings menu. Alternatively, press Windows Key + I.
Click on 'Apps' from the main Settings menu, then select 'Default apps' from the left-hand navigation pane.
Scroll down to the bottom of the Default apps page and click on the text link that says 'Choose default apps by file type'.
Scroll down the alphabetical list until you find the '.pdf' file extension. Click on 'Microsoft Edge' next to it, and select your preferred PDF reader from the pop-up list.
Change Default PDF Viewer Using the 'Open With' Context Menu
A fast alternative to update your default PDF application directly from the file explorer.
Use WPS PDF to Effortlessly Manage Default Settings and Edit PDFs
WPS Office includes a powerful built-in PDF reader and editor that provides a seamless, feature-rich alternative to Microsoft Edge. Within WPS Office, you can easily set and lock it as your default PDF application to bypass Windows 10's tendency to revert to Edge, while enjoying advanced tools like text editing, merging, and digital signatures.
- 1. Download WPS Office: Download and install the free version of WPS Office from the official website.
- 2. Open PDF Settings: Launch WPS Office and navigate to the global Settings or the dedicated PDF tools section.
- 3. Set as Default: Locate the 'Set as Default PDF Reader' option and click apply to register it with your system.
- 4. Confirm Prompt: If prompted by Windows, confirm WPS Office as your default application to prevent Microsoft Edge from taking over.
Frequently Asked Questions
Why does Windows 10 keep changing my default PDF viewer to Edge?
Windows 10 may reset default applications to Microsoft's native apps, such as Microsoft Edge, after major system updates, feature upgrades, or security patches to promote their own ecosystem.
Does Microsoft Edge offer the same features as a dedicated PDF reader?
While Microsoft Edge can reliably view PDFs and perform basic markups, dedicated software like WPS Office provides advanced capabilities such as deep text editing, format conversion, form filling, and OCR.
Can I uninstall Microsoft Edge to stop it from opening PDFs?
It is highly discouraged to uninstall Microsoft Edge because it is deeply integrated into the Windows 10 operating system. Reassociating the .pdf file type to your preferred application is the safest and most effective method.
How do I lock my default PDF viewer from changing permanently?
Windows 10 does not have a native feature to permanently 'lock' default apps against system updates. However, setting the default via the 'Choose default apps by file type' menu provides the strongest association, and using dedicated PDF software that monitors its default status can help maintain your preference.
