2. Run a System File Checker Scan

  • Open the Win + X menu with the Win + X hotkey.
  • Click Command Prompt (Admin) to open an elevated Command Prompt.
  • First, input the following line, and press Enter:
    • DISM.exe /Online /Cleanup-image /Restorehealth
  • Then you can enter sfc /scannow in the Command Prompt, and press the Return key.

  • Expect the scan to take about half an hour. Restart Windows if the scan repairs system files.

Corrupt system files are a probable source for the Event ID 1000 application error. As such, the System File Checker could feasibly resolve the issue.
