I have a machine with a Radeon HD 5450 that runs fine when I install the legacy Catalyst software and drivers. However, recently Windows 10 has been automatically installing Adrenalin overnight and removing Catalyst. I can fix it by running the Cleanup utility and reinstalling but Windows 10 keeps removing Catalyst after a day or two. Is there a way to prevent Windows 10 from doing this? I disabled automatic driver updates in the Windows 10 settings but all that seems to do is prevent Windows from adding Adrenalin while it continues to remove Catalyst.
