Among other options, installing and updating Windows 10 with ISO files has its own meaning. The ISO file can be used for a fresh installation, repair upgrade, or edition upgrade.

In the case of the latter two, users reported a hurdle where the installation starts fine, but after the “We get some stuff done” screen, they get the following error:

The setup program could not validate the product key

Now we can't do anything other than reinstall at this point, even though the system can be rebooted to the original settings.

2. When prompted, select the drive you want to clean and click OK.
3. In the Disk Cleanup dialog box, in the Description section, select Clean up system files.
4. When prompted, select the drive you want to clean and click OK.
5. In the Disk Cleanup dialog box, on the Disk Cleanup tab, select the check boxes corresponding to the types of files you want to delete, and then click OK. To erase data from a previous Windows installation, select the Previous Windows Installations check box.
6. In the message that appears, select Delete files.
7. In File Explorer, go back to your computer, select the drive you cleaned up, and then select Refresh. If you need more space (the reader is always highlighted in red), skip to the next tip.

Then proceed as follows:

• Press the Windows + X button
• Click on the Command Prompt (Admin).
• Type each command at the command prompt, then tap Access when the scan is complete.)
  • Dism / Online / Cleanup-Image / CheckHealth
  • Dism / Online / Cleanup-Image / ScanHealth

Disable Third Party AV

If you use a third-party security package that tends to be overprotective, it may break the connection between the update and external servers.

If this scenario applies to you and you are using a third-party suite that might affect the update, you should try the update again after disabling or uninstalling the potential antivirus manager.

Si se encuentra en esta situación, primero desactive la protección en tiempo real y verifique que la actualización be exitosa. Básicamente haga clic en el icono en la barra de tareas de su AV y busque una opción que desactive la protección en tiempo real.
