Distribute upf for existing users

Hi

I've made some changes to the user preferences I want to distribute to all our users in an easy way.

I read here that the upf should always be deleted before a product upgrade, so there should be an easy way to do this?

And I also read here on a way to distribute the upf:
https://communities.bentley.com/products/microstation/w/microstation__wiki/33635/distribute-standard-user-preferences

But this will never work in an organization. Getting all users to follow those steps is impossible. 

I found something here about MS_ALWAYS_CREATE_UPF but I don't get it to work with connect edition, is that variable not valid anymore?

Also, using the default-button in the preference-dialog don't seem to use the file defined by the MS_USERPREFSEED variable? 

Is there maybe a keyin or a short vba-command to restore the user preference from the default. 

I guess my last option will be to direct the MS_userpref variable to a read-only localtion to make sure I can controll these settings. 

Running OBD CE update 8 (MS CE U15)
