If PDFs are opening with a web browser or different app that the one you want on your computer, you can change the default app that PDFs open with.
NOTE: The below example will change the default app for PDFs to use Adobe
Acrobat DC. It can be Adobe Reader or any other PDF app, so long as it is
- In Windows Explorer, locate a PDF file.
- Right-click the PDF file, then select Open with then Choose another app.
- In the app selection screen, check mark Always use this app to open .pdf files, then make sure Adobe Acrobat DC is highlighted. Click OK.
- The PDF file should open in Adobe Acrobat DC.
Subsequent PDF files, when opened in File Explorer or from other apps, should then default to use Adobe Acrobat DC too.
