A dedicated free PDF reader will let you do so much more than just open documents. If you want to merge several PDFs, convert them to a different format, extract images, tweak text or split them into individual pages, there's a free PDF reader that will make it straightforward.
Once you've installed a new PDF reader, it will display a prompt asking if you'd like to make it your default PDF reader. We recommend leaving your settings as they are until you've had a chance to try the new reader and see if it's right for you.
If you're satisfied with its performance, you can make it your default PDF reader by right-clicking one and selecting 'Open with'. Browse to the EXE file for your new PDF reader, check 'Always use the selected program to open this kind of file', then click 'OK'.
