Change Default PDF Reader in Windows 10

If you are trying to open a PDF from an Internet Page and it is opening in Chrome instead of Acrobat Reader, it is because Chrome is your computer's default PDF Reading program.

1. On the Start menu, select Settings. 

2. Type Default into the Search box and choose Default app settings.
