Problem:

Windows 10 ignores the file association settings that are set in the registry

Symptoms:

After a user logs into a Windows 10 desktop, Default applications will be reset to Windows defaults (e.g. such as Acrobat or Chrome back to Microsoft Edge). The Windows 10 Action Center may also show many notifications saying the file extensions are reset.

Possible Resolution(s): 

Note:The following settings have been included in ProfileUnity 6.7 configuration Templates.

To save the Default App settings that a user has chosen, additional rules will need to be added to export/save and import the user's choices.

In the Portability Management page create a new portability rule set.

  • Name:
    Windows 10 File Assoc
  • Registry Rules:
    None
  • File System Rules: 
    • Operation: Merge
    • Folder: User Profile
    • Path: AppAssoc.xml
    • Click on Add then click on Save.

Edit the configuration that is used with your Windows 10 machines.
