I will show you how to change the “Computer Name” portion of your Windows 8 File History backups. This method applies to the following scenarios:
- You replaced your old computer, but would like to continue using the same File History Backup
- You changed your Computer Name AFTER initially setting up File History
- Navigate to
C:\Users\<Username>\AppData\Local\Microsoft\Windows\FileHistory
- Open Config1.xml and Config2.xml in Notepad for editing
- Replace all occurrences of “OldComputerName” with “NewComputerName”
- Save Config1.xml and Config2.xml
- Do the same for Config1.xml and Config2.xml files in
<backuplocation>\<Username>\OldComputerName\Configuration
- Rename <backuplocation>\Username\OldComputerName folder to “NewComputerName”
* Make sure you close the configuration files, otherwise you’ll be prevented from changing the folder name
The File History app MAY say that there was an error with your backup – if so, you can just point File History to your “new” backup location, and things should resume as normal.
