I have a RDS 2012 R2 setup that I connect clients to through the RDWeb URL. 99% of my clients are Windows 7, and the app we are using has a logon window that would be invisible when the users launched the app. I figured out that if I uninstalled KB2830477, then the logon window would become visible to my windows 7 users. So I removed the KB on all my clients, and everything was happy.
Now, I'm starting to get some Windows 10 clients, and they are having the exact same issue. The app launches fine, but the logon window is invisible. You can actually click where the username/password is supposed to be entered, and enter your credentials (this was also how it was for win7 clients until I removed the KB), and then login and everything seems to work fine. But the initial window is invisible. I have tried removing any Windows 10 updates, but this does not seem to fix the problem. Any ideas on a fix for this?
