Servicing FBWF-Protected Devices

  • Artigo

Servicing the image on an FBWF-protected device requires special care, depending on the files being updated.

To modify files in use, to modify the registry, or in update scenarios that require reboots, use the following procedure:

  1. Disable FBWF
  2. Reboot
  3. Service the image
  4. Enable FBWF
  5. Reboot

To enable and disable FBWF, use either the FBWF APIs FbwfEnableFilter and FbwfDisableFilter or the following FBWF Manager commands:

fbwfmgr /enable

fbwfmgr /disable

For servicing scenarios where affected files are not in use, and where registry modifications are not required, use FBWF to commit the changes after they are applied. For example, use FBWF to commit updates to the signatures used for virus detection.

Commit file changes using either the FBWF API FbwfCommitFile or the following FBWF Manager command:

fbwfmgr /commit [volumename] [filepath]
