attrib -h -s -r c:\windows\system32\catroot2
attrib -h -s -r c:\windows\system32\catroot2\*.*

  2. Press Enter after each command.

This will give write access to Catroot2 folder to Windows Update program.

These are the two main services connected to update Windows 10 or 8.1 to the latest version. If they are not working, then also error code 80246005 can occur.

You can start them. Otherwise, restart them.
