8. Restore Windows Registry

The “Bad System Config Info” error can also be related to problems with the Windows Registry. The Windows Registry is basically a huge internal database containing important, machine-specific information, related to almost anything in the system:

  • System hardware
  • Software and drivers installed
  • System installation
  • Profile information

Restoring Windows Registry from backup will remove any errors. However, there is a problem with this fix. As of Windows 10 version 1803, there is no automatic Windows Registry backup. Before version 1803, Windows will back up the Registry every 10 days through the RegIdleBackup service.

Microsoft stopped automatic backups to reduce Windows 10 footprint. Therefore, Microsoft recommends that you use a system restore point to repair the corrupted registry. Before you start fixing this error, you can check to see if you have a backup of the Windows Registry to restore.

Go to C: Windows System32 config RegBack. This folder contains the Windows Registry backups. If the file size shows zero, you cannot use this backup method and should move on to the next section.

If not, read on to learn how to manually restore the Windows Registry.

9. System Restore

If the methods above didn’t solve the problem, try a system restore. Refer to the Windows System Recovery Guide article for how to restore.

10. Reset Windows 10

This is probably the last method to fix “Bad System Config Info” error if the above methods are not working. 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 for how to do it.

I wish you all success!
