That depends on what operating system you have. On the Mac, you would right-click (or Ctrl-click) on any PDF file, then select 'Get Info'. On the new dialog that pops up, you would go to the bottom and select 'Open with' to your Adobe Acrobat Pro. In this guide, we will use Adobe Acrobat in the demo to show you how to change a different PDF reader in Windows 10. Make Adobe Acrobat as the default PDF viewer from system settings. Click the Start button in Windows 10, select Settings from the pop-up menu. The Windows Settings dialogue pops up, choose Apps Default apps. Thanks for your reply. I have Adobe Reader installed and the 'Open with' tab is already set to Adobe Acrobat Pro but the 'Change All' button is dimmed so I'm not able to change all of them back to the Adobe default pdf image. I'm thinking that since I changed it at one time (from Adobe icon to preview) that maybe the pdf's I download from now on will have the Ado. Go to the File menu, select Open, then browse to a PDF file on your Mac and open it with the Acrobat Reader or Pro. It will then prompt you to make make Acrobat Reader or Pro as the default application for PDF files on your Mac. Simply click Yes button to set Acrobat or Reader as the default PDF viewer on your Mac. The option to change your PDF viewer opens when you right-click on a PDF on your computer and select 'Get Info.' The default PDF viewer is Preview on Mac computers, but you can switch this to.
Both Acrobat and Reader can reside on the same machine, and the default handler can be set in the following ways:
Set the default handler at install time.
Configure the installer prior to deployment via the Wizard or command line.
After a product install, choose Preferences > General > Select Default PDF Handler.
Windows 8-10¶
System requirements¶
Acrobat and Acrobat Reader: 11.x-DC
Supported Platforms: Windows 8 and above
The problem¶
Admins often want to reliably set Acrobat and Reader as the default PDF owners on their organization's desktops. Since Windows 8, it has become more difficult for applications to take ownership of certain filetypes. Even when admins have a method for setting a default handler (described above), once the application is installed end users can change the file type associations via the Control Panel or with Right Click > Open With. Additionally, other applications sometimes force Windows to show an application selection dialog when a user clicks on a file, thereby allowing users to select a different application for that file type. Thus, since Windows 8, admins have little control over file type associations after installing an application.
Solution 1: DISM¶
Deployment Image Servicing and Management (DISM) is a way to enforce file type associations. While it remains difficult to prevent users from selecting alternative default applications, Microsoft addresses this problem by providing DISM as a way for admins to reinstate the defaults when a user logs off and on.
While DISM is a command-line tool that is used to mount and service Windows images before deployment, it can also be used to set file type owners on Windows 8 and above. Admins can use the default application association-servicing commands to import, export, list, and remove the settings that specify which application opens a file based on the file name extension or protocol. Microsoft provides many DISM command line options for performing these steps.

Solution 2: GPO policy¶
You can also enforce the filetype via GPO policies. Using Group policy admins can force file associations each time a user logs in. This way even if a user changes the default PDF handler in a particular session or an OS update changes it, the next time the user logs in, it will be changed back to what the admin has specified.
To set the file handler via a GPO:
Download the sample file association files. These files include all the file types supported by Acrobat and Reader. To create your own XML files:
Run an elevated command prompt on a machine that has your default application set correctly.
Type
Dism/Online/Export-DefaultAppAssociations:path>AppAssoc.xml
. This creates an XML file that has all your file types and their current associations.Edit the XML file to include only the file associations that you wish to enforce.
Note
You can create different files for different groups in your organization. For example, one group may use Adobe Reader as the default while another uses Acrobat.
Place this XML on a shared network location or push this XML to all your machine-specific locations via a script. For example,
C:WindowsSystem32
(do not use a user-specific location).Set the XML configured with your preferences in a Windows 8 Group Policy setting, and enable the setting as follows:
Open up the Group Policy MMC (open a command prompt and type
gpedit.msc
) on your Server 2012 instance.Locate the policy under
ComputerConfigurationAdministrativeTemplatesWindowsComponentsFileExplorerSetadefaultassociationsconfigurationfile
. This policy specifies the path for the XML file that can be either stored locally or on a network location.
Note
This is a machine-level policy. Where is the mod folder in minecraft. It is not possible to create user-level policy.
Enable the policy, and specify the location where you have stored the XML file. The corresponding registry entry is

Limitations¶
Bluestacks root mac os x. The end user machine needs to be domain-joined for this method to work.
Users can change the file associations during the current session. However, admin settings are reinstated at next logon.
As of 5th Feb 2016, it is a known limitation of Windows 10 that when new user is created on the machine after enforcing the GPO Policy, then on first login ownership is not set. However, the correct settings are applied on subsequent logins.
Command line control (pre DC)¶
At install time, the last installed product will wrest ownership from the existing install. Change this behavior by using LEAVE_PDFOWNERSHIP=YES during a command line install.
Resetting the default PDF handler¶
To make Reader the default PDF handler after installing Acrobat, find and run ADelRCP.exe in elevated mode. ADelRCP.exe is Acrobat's PDF handler program for Windows.
