Strange issue has come up since updating to 1803. There are times that an update is available for an application I have installed and you get the "do you want to update" prompt when you launch it. Use to work like a charm, but since the 1803 update more than half of them fail with an error message that says something about not being able to replace the *.exe (if I remember correctly, it's usually the main application's *.exe). If I download the update from the web site and update that way everything works correctly. This morning it even happened with Samsung Magician and I remember it happening with CCleaner a few days back. Any ideas?
