Windows never fails to give surprises. Windows always fails to give surprises. One hour ago, out of the blue (pun intended) my Windows 10 went to the blue (screen of death) of some VIDEO_TDR_FAILURE. Maybe I was pushing the system to its limit, I thought. So naturally I rebooted. To my horror, the system now comes directly to another blue screen, saying “BAD_SYSTEM_CONFIG_INFO”.

The system automatically went through some diagnosis and to no avail. I rebooted to safe mode, to no avail.

According to Microsoft, “This bug check indicates that there is an error in the registry.” The solution is:

  1. Try restarting the computer by selecting “last known good configuration” in the boot options.
  2. If the restart does not fix the problem, the registry damage is too extensive. You must reinstall the OS or use the Emergency Repair Disk (ERD) that you previously created by using the Windows Backup tool.

Well, that is very informative – but indeed it is, which tells us to look into the registry. So I boot into the command prompt, go to D:\Windows\System32\config which is where the registry is stored. In this directory there is a hidden folder called RegBack which is a backup of the registry. That is our savior.

So I created another backup folder, copied everything into the backup folder, and used the files in RegBack to overwrite those in D:\Windows\System32\config. Reboot, and the system is back to life.
