I hope someone can help me. My mom recently got a new laptop and I have set everything up for her. But I cant update windows. I think I may have installed malwarebytes too soon and now I cant update Windows Defender (kb4052623). I have gone to https://www.catalog.update.microsoft.com/Search.aspx?q=KB4052623 and the .exe files will not load. I checked AppLocker and there is nothing there. I am at a loss and don't know what to do. I keep googling and finding no solutions. Can anyone help me?
