What Causes Fatal Error C0000034 on Windows 10?

The fatal error C0000034 typically occurs while you’re installing an update on your Windows OS. Instead of restarting after the Service Pack installation, the computer shuts down. The other reason would probably be repetitive update installations that come with the Service Pack.

Here are some of the ways you can fix this error:

  1. Launch Startup Repair
  2. Utilize the Troubleshooter for Windows Update
  3. Refresh the Components of your Windows Update
  4. Clean up your Windows Registry

1) Launch Startup Repair

  1. Begin by restarting your computer. While it’s starting up, reboot it again.
  2. You will see an error report and will be prompted to “Launch Startup Repair.” If you do not have this program installed on your computer, use the installation disc of your Windows OS. Boot from the CD and continue the process from there.
  3. Once the Startup Repair runs, click Cancel.
  4. When you click Cancel, a dialog box will show up. Click Don’t Send and then click the hyperlinked “View advanced options for recovery and support.”
  5. A new window will open. At the bottom, you will find the Command Prompt.
  6. In the Command Prompt, type “%windir%system32notepad.exe” (no quotes) and hit Enter.
  7. By running this command, you will be able to open Notepad. In Notepad, go to File and click Open.
  8. Go to the list of files that Notepad views and change it from .txt to All Files.
  9. In the file explorer, follow this path: C:\Windows\Winsxs (or whichever drive you installed your system on).
  10. Inside the Winsxs folder, search for the pending.xml file and copy it.
  11. You will paste the file in the same folder just to make sure that you’d still have a copy in case something happens to the original pending.xml file.
  12. Open the original pending.xml file. (You may have to wait for a while for the file to load because it’s huge.)
  13. On your keyboard, type Ctrl +F and search for the command “0000000000000000.cdf-ms” (no quotes).
  14. Delete the text below:
