Windows 10: File association problem Windows 10

I've associated .dok files to the program DesktopOK by GPO in order to load a desktop layout upon startup, so that new users can find an workable desktop layout instead of a pack of icons on the left.But it doesn't work. Although the file association script does its job correct values with correct progID "desktopokdoc" are set in both Ordinateur\HKEY_CLASSES_ROOT\.dok and Ordinateur\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dok\UserChoice Even exporting default file association from dism /online /Export-DefaultAppAssociations:"C:\DefaultAppAssociations.xml

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Links/associations not working


So, does no-one have suggestions or a solution to my problem?
The problem occurs when I double-click on a folder or link: 'This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel'.
I can only open them by right-clicking on the item and select 'Open' which is third in the list. Above that is 'Search' and on the top is 'cmd' (where 'Open would normally appear).
I've scoured the Net and tried several ways to cure this (including 'Default File Type Associations - Restore in Windows 10') but to no avail.
Any suggestions most welcome.
