The current problem update is KB4537821 which windows update fails to install and installing via dism gets us the error 80073712 Component Store Corruption. sfc /scannow shows no issues as does sfcfix. Trying dism /online /restorehealth shows a sources error even when we give it a valid wim file with the proper index. Reinstalling the OS is not an option due to the amount of applications installed and special configuration on this machine it would take us months to get it back up and running. Here is a link to the CBS logs: CBS.zip (55.71MB) - SendSpace.com Any help is greatly appreciated!
