BCD edit command

BCD (binary coded decimal) can be edited to resolve the windows ten bad system config info error. Because sometimes the system configuration gets corrupted by some apps. They alter the values of memory and processor, thus using enormous resources that cause such errors.

To fix this issue, you have to make a bootable USB of Windows 10 or the Windows that you are using. This is also called installation media. After making the bootable device, follow the steps.

bcdedit/deletevalue {default} numproc
bcdedit/deletevalue {default} truncatememory
These commands will delete the altered values and will set them to default. Thus, if there is an error that is being caused by these changes in value, then that can be removed using these commands.

Now reboot the system and error should have gone. If the error is still there, jump to the next solution.

  • Boot your computer from that device.

ren C:\Windows\System32\config\SOFTWARE SOFTWARE.old

The above commands will rename the folders, as the ren command is for renaming. We can delete these folders too, but who knows, if we need them in the future.

Now you have to create the new files or replace the old registry file. For that, enter the following commands.

copy C:\Windows\System32\config\RegBack\DEFAULT C:\Windows\System32\config\<//code>

copy C:\Windows\System32\config\RegBack\SAM C:\Windows\System32\config\

copy C:\Windows\System32\config\RegBack\SYSTEM C:\Windows\System32\config\

copy C:\Windows\System32\config\RegBack\SOFTWARE C:\Windows\System32\config\
