1. Restart Your System

This is the easiest way to fix the bad system config error. Start by switching your computer off and then turn it on again. Then, check if the issue has been fixed or not. Restarting your computer can fix several temporary issues and should be tried out before moving to other methods.

2. Run SFC and CHKDSK

Corrupt file systems can also cause a Bad System Config Info error that won’t go away. In such a situation you can run the Windows System File Check (SFC) that is an inbuilt Windows tool used for checking such errors. 

But, before you proceed with the SFC, we recommend you to run the DISM that can check if the SFC will run properly or not. Given below are the steps to do the entire procedure:

Step 1. Type Command Prompt (Admin) in the Start menu search box. Once the result comes, right-click on it and select Run as administrator.

Step 2. Enter the following command in the Command Prompt window:

DISM /online /cleanup-image /restorehealth

Step 3. Wait till the process is finished which can take up to 20 minutes. 

Note: Don’t panic if the DISM cleanup seems to have gotten stuck at times. Wait for it to finish.

Step 4. Once the procedure is completed, type in “ sfc/scannow” and hit the Enter button.

For a change, you could also go for the CHKDSK command. This too is a Windows system tool but unlike SFC, it will scan your complete drive for errors. 

If you want to use the CHKDSK command instead of SFC, simply go to the command prompt again as explained earlier. Then type in chkdsk/r and press the Enter key.

3. Restore the Windows Registry Via The Command Prompt

You can also get the Bad System Config Info error due to some problem with the Windows Registry. Follow the steps given below to restore Windows Registry and solve the bad config info error:

Step 1. If there is some data in the files in the RegBack folder, go for a manual Registry restoration. First, boot into the advanced start-up.

Another way of entering the Advanced Options is:

Open the Start Menu. Then, press and hold the Shift key and hit the Restart button.

Step 5. Now, you need to change the directory and restore it. The command prompt defaults to the address X:\Windows\System32. This is not the real location of your Windows installation.

Windows installs in the C:\ drive by default. But, it can be installed elsewhere if you specify some other location. Remember that the Windows recovery mode usually boots the Windows installation under D:\.

Step 6. Type in dir D:\Win* to locate the correct address of the Windows. If this is the correct drive, then the command prompt will list down the directory’s contents.

Step 7. Enter the following commands one by one and press Enter after each command:
