These commands will copy the registry backups and replace the old files. After running the commands, close Command Prompt and restart your computer.
9. Restore Windows Registry
The “Bad System Config Info” error can also be related to problems with the Windows Registry. The Windows Registry is essentially a giant internal database that contains important, machine-specific information related to almost everything in the system:
- System hardware
- Installed software and drivers
- System settings
- Profile information
Restoring the Windows Registry from a backup should clear up any errors. However, there is a problem with this fix. As of Windows 10 version 1803, there is no automatic backup of the Windows Registry. Before version 1803, Windows would back up the Registry every 10 days using the RegIdleBackup service.
Microsoft has stopped automatic backups to reduce the size of the Windows 10 footprint. Therefore, Microsoft recommends that you use a system restore point to repair a corrupted registry. Before you begin this fix, you may want to check to see if you have a backup of the Windows Registry to restore.
Go to C:\Windows\System32\config\RegBack. This folder contains Windows Registry backups. If the file size shows 0, you cannot use this backup method and should move on to the next section.
If not, read on to learn how to restore the Windows Registry manually .
10. System Restore
If the above methods do not resolve the issue, try performing a system restore. Refer to the article How to perform a system restore in Windows for instructions on how to restore.
11. Reset Windows 10
This is probably the last method to fix the "Bad System Config Info" error if the above methods do not work. Before resetting, create a backup because this process will delete all files in drive C. Refer to the article Summary of some simple ways to Reset Windows 10 to know how to do it.
