User File Type Association

Pascal Poumlstgens


Dear All,


we are currently migrating from W2K12R2 to W2K16 based on XenApp 7.15 LTSR using Full Desktops.

Many issues have already been resolved, but now we found out that User based FTAs are not getting saved.

There are many answers on the web, but nothing helped.


UsrClass.dat* had been removed from the Exlcusion list, but still the issue is available. Therefore exclusion has been readded again:



Anytime the user changes .htm for example to Firefox, it directly get's changed back to IE when the user logs off and on.

We are using a DefaultFileAssociation via Group Policy, where .htm get's assigned to IE.

Am I right that this FTA only get's applied only one time for a new user or does it overwrite the settings anytime?


Registry export from http://kolbi.cz/blog/2017/10/14/user-file-type-association-roaming-on-server-2016-with-citrix-user-profile-manager/ didn't help, as Firefox (for example) doesn't have any entry there. The important keys are under HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt\UserChoice


Does anyone has any idea which could help?


Thank you very much!
