When I checked for updates on Windows 10, version 2004, Windows Updated indicated that there were optional updates available. I selected the update and clicked "Download and Install." Windows checked for updates again and displayed the same results without installing the update. I repeated this a few times to no avail. Please help.
Error code 0x8024004C.
I ran sfc/scannow and retried the update. That fixed it. Source: 800error
