Here is how to tell if you have the problem: Click on the Start Menu and choose Control Panel. Change View By to Small Icons and click on Indexing Options. Click on the Advanced button. Click on the File Types tab. Scroll way down to pdf and you will probably see Registered IFilter Is Not Found. Open File Explorer and navigate to a folder containing your PDF file. Right-click on a file and choose “Open with Choose another app”. A pop-up will appear that will let you choose a program for just one time. Or you can also select the “Always use this app” link to make it permanent. From this window, choose the default PDF reader of your choice.
