After that, close the command prompt window and restart the computer. It is supposed to repair the corrupted system files that prevent you from entering the Windows system properly, but if the problem is not solved, we will move on to the next solution:
- Repair data record
Sometimes some problems in the "Registry Files" event log cause the same problem, but it is easy to solve, just install a flash drive with the Windows system on it, then choose Troubleshot, then Advanced option, then Command Prompt, and inside the command prompt window you will write these commands with a space between each command and the other by clicking the Enter key.
cd C:\Windows\System32\config
ren C:\Windows\System32\config\DEFAULT DEFAULT.old
ren C:\Windows\System32\config\SAM SAM.old
ren C:\Windows\System32\config\SECURITY SECURITY.old
ren C:\Windows\System32\config\SOFTWARE SOFTWARE.old
ren C:\Windows\System32\config\SYSTEM SYSTEM.old
After that you will need to type these commands as well.

These commands are to back up the registry files and replace the old ones. Close the command prompt window and restart the computer.
- Reset Windows 10
This is the last attempt to solve the Bad System Config Info problem if all the previous solutions failed to get rid of the error message, but remember that this attempt may delete everything inside the C system file, so it is possible to take a backup first before re-formatting.
From the Start menu, click on Power Option, then long-press the Shift key, then choose Troubleshot, then choose Reset This PC, then choose Remove every Thing, then Only the drive where Windows is installed, then Just remove my files.
Click on Reformat and wait until the process is complete. This way, you will get a new Windows 10 system without errors. This way, you will get rid of all the programs or processes that were causing this problem.
