Anyone know a way to disable this popup banner when launching Citrix resources. Tried to disable all notifications in Windows for Citrix Workspace App but nothing changed. Users claim that it's annoying and often the banner get stuck and covers their actual work.

This key is not recommended and can be removed /may not work in future releases. Additionally it has more granular progress messages and multiple new features for better troubleshooting etc as part of this. Disabling this will cause none of that to work. This is the launch progress dialog this will come in center even if you disable and wont have many functions. If main issues is it is getting stuck in some scenario that can be logged as support case to diagnose.
