Hi Softwaremaniac, the update '2018-12 Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB4471318)' continues to fail but, thanks to you, other later updates have installed successfully. Do I need this update? If I don't install it, will future quality rollups have a problem? Is there a setting I can change to tell the system that the upgrade is installed? Do you have any other suggestions? Thanks for your help and have a happy Christmas and a productive New Year.
