Windows 0x80070003: Fixing Path or File System Errors During Update

The 0x80070003 error in Windows usually occurs during an update or installation process, indicating that Windows Update cannot find or access the necessary files.

This error is typically caused by problems with the update path or corrupted system files.

To resolve this error, start by resetting the Windows Update components.

Open Command Prompt as an administrator and type the following commands to stop the update services: net stop wuauserv and net stop bits.

Then, go to C:\Windows\SoftwareDistribution and delete all files in the folder.

Restart the update services with net start wuauserv and net start bits.

After this, run the Windows Update Troubleshooter by going to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.

If the error continues, run the sfc /scannow command in Command Prompt to fix any corrupted system files, followed by DISM /Online /Cleanup-Image /RestoreHealth to repair any damaged Windows image files.

Finally, if none of these steps work, perform a clean boot to eliminate any software conflicts.
