Win10 cancels the PDF file by default. The method is opened in Spartan browser.

Win10 has a built-in reader application. This is a great way to view PDF files, but I don’t know why PDF files default to Sparta. The browser is open, how to solve this problem?

Operation steps

In the first step, right-click on the pdf file and select “ldquo; attribute” from the menu.

In the second step, in the pdf file properties dialog box, under the General tab, click on “Change” after the open method.

The third step, in the "How do you want to open this .pdf file from now on?" window, select "Reader”.

If you don't know where the Win10 reader app is or how the reader opens, you can click on the link to see it, so you don't have to open the reader from the file every time.
