Fix the Windows 10 Anniversary Update error code 0x80070057
The symptoms of the error are a failed install. It will either stall on file download or install up to 2% and then fail. Here’s how to fix it.
1. Navigate to Settings, Update & security and Windows update.
2. Click ‘Learn more’ at the bottom of the pane. This should take you to the Microsoft website.
3. Click ‘Get the Anniversary Update now’. A download link should appear with the file ‘Windows10Upgrade28084.exe’.
4. Download the file while watching it and as soon as it hit 100%, turn off the internet either by unplugging your LAN cable or disabling your network card.
5. Install the update and it will likely freeze at 2% again. Wait around 30 seconds and then turn internet back on. The install should then proceed as normal.
Like I said, I haven’t seen this error myself but I have it on good authority that it works. Let me know below if it doesn’t work for you.
