Additional considerations

  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.

  • You must be running as the local computer administrator to save the backup file in the %Windir%\System32\Wbem\Repository folder. Otherwise, you can save it in the Documents folder for the account profile.

  • When you click Back Up Now to back up the repository manually, you can back up to a specified file name, and later restore from that saved file. This approach can be useful if you want to save a specific configuration of classes. You also can run the Winmgmt command at a command prompt and restore from the saved file. For more information about using the Winmgmt command, click Start, click Run, and type winmgmt /?
