Description of error code 0x8007045b and where it may occur in Windows systems

To resolve this error code 0x8007045b, follow these steps:

  1. Run the sfc /scannow command in an elevated Command Prompt to check for corrupt system files.
  2. If step one does not resolve the issue, proceed by running the DISM tool with the following commands: first run dism.exe /online /cleanup-image /scanhealth, then if it returns errors, use dism.exe /Online /Cleanup-Image /RestoreHealth.

  • In scenarios where Deployment Imaging Service and Management Tool (DISM) commands are executed improperly or fail due to internet connectivity issues or server downtime.

Additionally, this error might appear if there is a misconfiguration in Group Policy settings that blocks access to certain update files. It could also be triggered by outdated drivers conflicting with newer system updates.
