0x80070002 (File not found): what it means and how to fix it

Updated Oct 10, 2026 · Checked against Microsoft documentation · How this page is made

Quick answer

This error means Windows cannot find a specific file or folder required to complete an update or installation. It is most often caused by missing system files, incomplete previous updates, or corrupted registry entries. Start by checking your system logs to identify exactly which file is missing.

What it means

Understanding Error 0x80070002

When you see error 0x80070002, Windows is telling you that it tried to perform a task—usually installing an update—but stopped because a necessary piece of the puzzle is missing. The code literally translates to "The system cannot find the file specified."

This happens because the update process relies on a specific sequence of files, folders, and registry instructions. If a previous update was interrupted, or if a critical system file was accidentally deleted or moved, the update process hits a wall. Windows cannot "guess" where the missing information is, so it halts the process to prevent further errors or system instability.

How to find the source of the problem

Because this error is generic, it does not tell you exactly which file is missing. To find out, you need to look at the CBS (Component-Based Servicing) logs. These are text files that record the details of update attempts. You can find the main log at C:\Windows\Logs\CBS\CBS.log. When you open this file, look for lines containing "Error" or "Failed to find file." These entries will typically name the specific file or registry key that caused the failure. Once you know the name of the missing item, you can focus your efforts on restoring that specific component rather than guessing at a solution.

Common causes

  • Incomplete or interrupted previous Windows updates.
  • Missing or corrupted system files in critical directories.
  • Registry entries pointing to files or services that no longer exist.
  • Missing DLL files within the Windows Side-by-Side (WinSxS) store.
  • Driver installation failures during a cumulative update.
