Changing the default PDF app on Windows

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 
already installed.

1. In Windows Explorer, locate a PDF file.
   
   
2. Right-click the PDF file, then select Open with then Choose another app.
   
   
   
   
3. 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.
   
   
4. 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.
