I'm not sure this is a Win 10 problem however it appears to because I had to replace Windows Media Center with Hauppauge WinTV 8 to access my off-the-air TV channels using my Hauppauge TV receiver card. There are two startup links and each bring up a window be manually authorized before boot up can complete. I can make that go away by changing Internet Options, Security Settings, Launching applications from Prompt to Enable (not secure). Then there is a warning message on start up but it doesn't require any manual action. That doesn't seem like a very good solution to the problem. Is there a way to set an exception for those links?
