Getting error 0x80070057

Just out of curiosity, did you guys attempt the update after having been notified of the update, or did you download the upload file (Windows10Upgrade28084.exe) from Microsoft?

I got a slightly different error (0x80070005) after Window10Upgrade28084.exe failed to validate my product key in spite of Win 10 being correctly activated.

Tried it twice with the same results. Possibly I should have run it with elevated permissions even though my account already has administrator privileges. Am now trying with the MCT to see if that makes a difference.

Same prob with my Surface Pro 4, spent over 2hrs onto helpdesk, they took control of my machine and still they couldn't rectify this issue. This morning I reset the machine, so no 3rd party software. Guess what still the same error code 0x80070057.........
\any help would be appreciated

Joining in on this thread so we can finally find a fix for this! Having the same issues even after going over ALL the solutions posted on Reddit and the Microsoft forums. I'm using the Windows 10 Upgrade Assistant Tool and everything is fine until it starts to actually install Windows 10. It gets to 2% before giving me the same error code number.

Ditto! I too am looking for the solution.

Success! What I did was uninstall the "Windows 10 Upgrade Assistant" that I had previously installed by going to Settings>Apps & Features. Then I rebooted just for luck. Then I went to the Windows Downloads page (https://www.microsoft.com/en-us/software-download/windows10) and just below where it says, "Looking to install Windows 10 on your PC?" I clicked the Download Tool Now button. Don't know why it worked, but it did!

Success!!!!!!!! Using Microsoft Media Creation Tool and doing a clean install keeping my settings and Apps

I found the solution that worked for me.

I ran the Windows 10 Upgrade Assistant Tool and after it started, I disabled my network connection (LAN or WLAN) by putting it into airplane mode. The Anniversary update then ran flawlessly! Apparently there is some conflict between Windows Update and the Windows 10 Upgrade Assistant Tool that prevents the upgrade with a network connection.

I don't have wireless on my desktop so I guess i would just disconnect the cable from my router to the back of my desktop?

Yes, you could do that, or you can disable your network connection from the Control Panel.
