Have tried every solution under the sun, with no luck for almost 18 months. Update fails on KB4033631 and KB4049411, according to Update History. Yet, Update Status says: "Your device is up to date. Last checked: 11/10/2018, 7:52 PM." sfc /scannow does not work and returns: "Windows resource protection cannot start the repair service." Computer is a Toshiba Kirabook laptop, model PSU8SU Hardware Abstraction Layer Version = "10.0.14393.206" The experts on this forum have solved issues with very similar characteristics. I would be grateful for help with mine.
