You might have gotten trapped by that darned alphabetical order and a little Google overreach. Disable the Protected Mode in Acrobat Reader.
How to FIX: Acrobat Reader Cant Print PDF files in Windows 10 2004.
Just keep this tip in mind if PDFs start opening unexpectedly in Google Chrome. If you could not print PDF documents in Acrobat Reader DC, follow the instructions below to fix the problem. This article has a couple of other ways to do the same thing. That opens the window shown above, where you can browse to Acrobat. You can also right-click on a PDF and choose Open With / Choose Program. Adobe leads you in through “Properties” on the right-click menu of a PDF file. This is not the only way to make Acrobat the default PDF program, by the way. I didn’t have to think about this until the last few months when I realized that PDFs were opening in the wrong program after I finished my work. I might be wrong but this feels like a recent change. It’s tempting to choose it first – it’s in the A’s at the top of the list, right? Recently, though, Google made a change and now Google Chrome sets itself as the default PDF viewer if you click on “Set this program as default.” If you choose Acrobat first and then choose Chrome, it undoes the PDF default for Acrobat.
I usually install VLC Media Player and set it as the default for all media files. At least I’ll make sure to give Google Chrome and Outlook control of all their defaults.
Internet links will open in the Edge browser. For example, certain types of email links will open in the built-in Windows 10 Mail app instead of Outlook. Windows 10 has some odd choices of defaults even after those programs are installed. Most small business users expect to use Google Chrome for web browsing, Microsoft Office (Outlook/Word/Excel) for mail and documents/spreadsheets, and Acrobat DC or Acrobat Reader for PDFs. This is a quick note for people who want to use Acrobat DC or Acrobat Reader to open PDFs, using “Set your default programs” in Control Panel. One of the first things everyone does with a new Windows 10 computer is install basic programs and utilities and set defaults so files open in the right program.
