  1. C:\windows\system32\config\regback empty - batch file to export registry in Windows 10

    I was doing some research on this and it seems that Windows 10 since at least 1803 no longer makes backup copies of the Registry hives and places them in C:\windows\system32\config\regback. I also notice that the REG.exe command is available in the windows recovery environment(winre). So my question is this. Since Windows 1809 no longer creates this backup I would like to be able to create a simple batch command file that I can run within the winre and make a complete copy/backup of the total registry, so I would then have a backup to restore from if need be. If you can provide me with the reg save/restore commands, or reg import/export commands to accomplish this goal. Also WHY doesn't windows 10 1803/1809 not perform this backup anymore anyway? bad move Microsoft! System restore is not an option to do full registry backups as System restore has proven, at least to me to be faulty and flaky, but then that's just my 20+ years of windows experience. There used to be a REGBACK.exe in the old Windows NT Resource Kit that worked great but it's not available anymore either. Using REG Export while windows is up does not create a complete total registry backup. Well, any help or assistance with this matter will be greatly appreciated. TIA

    Update: Can you do something like this in winre:



    The above points to D: and not C; as in winre X: is the winre drive and D: is my actual C: drive

    I would first enter D: at the x:. prompt to change directories

    that would put me at D:\Windows\System32 the cd to D:\windows\system32\config

    type: Dir and that should show me all the Registry Hives?

    I forget where the NTUSER.DAT file is specifically?

  2. Bad system config info windows 10 on boot up!!!

    Finally found the only solution that works. From:

    How To Fix The Bad_System_Config_Info Error In Windows 10

    Fix The Windows Registry

    Boot from a Windows 10 USB/DVD and launch Command Prompt. It is better to use the DVD for this purpose. After that, follow these instructions:

    • Use the following command:

      CD C:\Windows\System32\config

      (here C is the partition where Windows is installed).
    • Enter the following commands one by one to rename these files with the .old postfix:

      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
    • Enter the following commands one by one to copy registry backup files to your current registry folder. This completes the manual restoration of your computer’s registry.
      • copy C:\Windows\System32\config\RegBack\DEFAULT C:\Windows\System32\config\
      • copy C:\Windows\System32\config\RegBack\SAM C:\Windows\System32\config\
      • copy C:\Windows\System32\config\RegBack\SECURITY 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\

  3. disk C problem

    Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.

    Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

    Please type below commands into Command Prompt and for each command you have typed press Enter key.

    Ren  C:\windows\system32\config\SAM         SAM.BAK  Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK  Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK  Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK  Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK     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\SECURITY    C:\windows\system32\config  Copy  C:\Windows\System32\config\RegBack\DEFAULT     C:\windows\system32\config  Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config
    This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.

    Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.
