We recommend that you restart your computer after running CheckSUR to ensure that all changes take effect. In addition, you should try to reinstall all software updates that could not be installed before. If CheckSUR has detected and corrected the cause of the errors, these updates will now be successfully installed.

Checking logs and removing patches

CBS is the abbreviation for component maintenance. CBS.log is a file that contains component logs when they are installed or uninstalled during the upgrade. If you see failed updates in CBS logs, it is better to uninstall patches that lacked assemblies.

When you open CBS logs, look for the words “ERROR_SXS_ASSEMBLY_MISSING” and see if there is a KB update for them. Uninstall it, reinstall it with Windows Update.

If there is no error, we recommend that you execute the command:

Dism /Online /Cleanup-Image /ScanHealth

The /ScanHealth option checks if the component memory is damaged. It records this corruption in the C:\Windows\Logs\CBS\CBS\CBS\CBS\CBS.log file, but no corruption is fixed with this switch. It is useful to know whether there is corruption and, if so, what it is.

CONCLUSION

Finally, if none of these fixes fix bug 0x8007373701, it is better to wait for Microsoft to release a fix that is expected soon. According to Microsoft, an update KB44979797935 also caused this problem.
