This error is only caused by one type of issue, and that is unfinished or corrupted files being present in the Windows 10 installation folder.

  • Files that are unfinished in the Windows 10 installation folder are a result of the download not processing correctly, therefore the update is not successful because your computer does not have the files that it needs.
  • Files that are corrupted in the Windows 10 installation folder are a result of either a faulty download or preexisting corrupted files that need to be purged.

Until your system is ready to download the new Microsoft Windows 10 upgrade, you will be unable to install the upgrade. As stated, you have the option of waiting for your system to prompt you to download (which means that your system has made the necessary changes to its own files and is ready for the upgrade), or you can use the following steps to correct the issue yourself.
