Microsoft Edge & Windows 10

Microsoft Edge is the new browser that ships with Windows 10, and is also the default system PDF reader by default.  Unfortunately, this viewer lacks the advanced features necessary when working with online fill-able forms.  In order to disable Microsoft Edge's PDF feature, you need to change the file association, which you can accomplish with the following steps (Video instruction is provided below):

  1. First, you must ensure that you have the latest version of Adobe Reader installed.  If not, download the application by clicking the "Get ADOBE READER" button above.
  2. From the Windows Start menu, scroll down to and click "Settings".  A "Windows Settings" popup window will appear.
  3.  Click on the "Apps" link.
  4. Click on the "Default Apps" link located in the left menu.
  5. Scroll down to and click on the "Choose default apps by file type" link.  You will see a progress bar at the top (it may take a few seconds, depending on how many apps you have on your system).
  6. Scroll down until you reach the PDF File type (.pdf) which is displayed in the left column.  You should see "Microsoft Edge" as the app name in the right column.
  7. Click on the Microsoft Edge icon and select your PDF Reader from the list (i.e. Adobe Acrobat Reader).
  8. Close the Settings popup window by clicking the red X (upper right), and you're done!

Note: With Windows 10 upgrades, please ensure that the Microsoft Edge reader has not been set as the default again. 

The video below demonstrates the steps outlined above.
