The motto for Windows 8 is apps and Microsoft wants to have an app for anything and everything. No wonder even for reading PDF documents, Windows 8 comes with an app called Windows Reader.

Windows reader just works fine for most PDF documents. But a lot of people either don't like it or want to use Adobe Acrobat Reader to view their PDF files. The problem is unlike earlier versions of windows, Windows 8 doesn't associate Acrobat Reader as default application for PDF files after installing it. So if you want to open all your PDF files using Acrobat Reader by default, here's what you need to do -

• Right click on any PDFfile and click "Properties".
• Click on "Change" button against the "Open With" option.
• You will get a new window which shows valid applications associated with PDF files. Just click on Adobe Acrobat.

That's it, all your PDF files will now open using Acrobat Reader on double clicking. Here's a video showing the steps in action -
