====== Windows Default Applications ======

Sometimes, for various reasons, the default application for certain types of files will get misconfigured.  This happens often enough that users should know how to rectify the situation themselves.

:!: Please note that this 'fix' (re-association) can be used for almost any app or any file-type that must be opened in Windows.  While the following example is for PDF files, the same situation might exist for many other file types as well.

===== PDF Files Opened by Excel =====

We frequently see where documents of the file-type ''.pdf'' get configured to be opened by Microsoft Excel, which can't actually view or edit PDF documents.

What we need to do is change the setting back so that PDF documents are opened by Adobe Acrobat DC again:

  - Use the file manager (''explorer.exe'') to browse to any valid PDF document
  - Right-click the PDF file -> ''Open with'' -> ''Choose default program''
  - Select ''Use this app for all .pdf files''
  - Select ''Adobe Acrobat Reader DC'' as the app to always use for PDF docs
