How to fix DISM Error 1009: Registry database is Corrupted.

Requirements: In order to resolve the dism 1009 error, you will need to boot your computer from a Windows installation media (USB or DVD).  If you don’t own a Windows Installation Media then you can create one by using Microsoft’s Media Creation tool.

• How to create a Windows 10 USB installation media.
• How to create a Windows 10 DVD installation media.

Method 1. Restore Windows 10 as it was before installing the updates.

The DISM error 1009, usually appears after an unsuccessful installation of a Windows Update. So, first of all cancel the installation of the updates. To do that:

1. Boot your system from a Windows installation media.
2. At the below screen press the SHIFT + F10 keys to launch command prompt. (or click Next and go to Repair My Computer > Troubleshoot > Command Prompt).

3. At command prompt, get a list of all drives, on your system with this command:

• wmic logicaldisk get name

4. Then find out which drive contains the "Windows" folder, by typing this command: *

• dir DriveLetter:

* e.g. To see the contents of the C: drive, type: "dir C:" (without quotes). If you cannot see the "Windows" folder on the C: drive, then continue to the next drive letter (e.g. "dir D:", "dir E:", etc.), until you see the "Windows" folder on one of the listed drives (from the above command).

[As you can see at the screenshot below, the Windows folder (at this case) is located at the D: drive.]

5. Once you find on which drive the "Windows" drive is located (e.g. at drive "D:" in this example), navigate to that drive by typing DriveLetter: + Enter.

6. Then create a scratch folder on the drive by typing this command:

• mkdir D:\Scratch

7. Then give the below command to rollback your system, after the unsuccessful update:

• DISM /Image:D:\ /ScratchDir:D:\Scratch /Cleanup-Image /RevertPendingActions

* Note: Change the drive letter D according to your case.

8. Once the above DISM command is executed, you should receive the following message on screen:

"Reverting pending actions from the image….
The operation completed.  Any revert of pending actions will be attempted after the reboot
The operation completed successfully."

9. Close command prompt and restart your computer. *

10. If Windows boot normally, then continue to your work. If Windows won't boot and tries again to install the updates, then:

1. Power off you PC.
2. Start again your computer from the Windows installation media.
3. Launch command prompt.
4. At command prompt give the following commands in order (don't forget to change the drive letter D according to your case):

• • del D:\Windows\SoftwareDistribution
  • del D:\Windows\WinSxS\cleanup.xml
  • del D:\Windows\WinSxS\pending.xml

5. When done, close command prompt and restart your PC. *

* Note: If the boot fails again, then boot again is WinRE command prompt and give the following commands (don't forget to change the drive letter D according to your case):

• chkdsk /r D:
• sfc /scannow /offbootdir=D:\ /offwindir=D:\windows
• dism /image:D:\ /cleanup-image /restorehealth

Method 2. Restore Windows Registry from Backup.

The next method to fix the dism error 1009, is to restore the Windows registry from the 'RegBack' folder. *

* Info: The 'RegBack' folder, (full path=Windows\System32\Config\RegBack), is the location where Windows stores automatically a backup of the registry files whenever the machine is starting up.

To restore the registry from the RegBack folder:

1. Boot your system from a Windows installation media and then follow the steps 1-5 from the method-1 above to navigate to the Windows drive. (e.g. the "D:" in this example).

2. First of all, take a backup of the current registry files, by giving the following commands in order. (Press Enter after typing each command):

• cd \windows\system32\config
• md Backup
• copy *.* Backup

3. Now navigate to RegBack folder by giving this command:

• cd RegBack

4. Then type DIR (to view the contents of RegBack folder).

5. Now see if any of the listed files has 0 (zero) bytes in their file size and proceed below according your case:

• Case A. If any of the listed files has 0 (Zero) bytes in its size, then stop here, and continue to the next method, because the registry backup files are useless or corrupted.
• Case B. If all the listed files, have a size different from zero (like in the screenshot below), then proceed to the next step.

6. Copy the registry files from the Windows\System32\Config\RegBack folder to Windows\System32\Config\ folder, by giving this command:

• copy *.* ..

7. When prompted, press A to overwrite the files in destination after giving the copy command.

8. When the copy is completed, type exit and press Enter to close command prompt.
9. Restart your computer and try to boot to Windows.

* Note: If the Windows fails to boot again, then boot again is WinRE command prompt and give the following commands (don't forget to change the drive letter D according to your case):

• chkdsk /r D:
• sfc /scannow /offbootdir=D:\ /offwindir=D:\windows
• dism /image:D:\ /cleanup-image /restorehealth
