Getting error 0x80070057

When trying to install the anniversary update I get to 2% and then I get this error 0x80070057. I need to know a simple way to correct this.

Had the same problem last night.

In my case, there was a constant "retry" of a Defender definitions update that was apparently getting in the way.

I ended up downloading the ISO straight from Microsoft, and running that did the trick.

I have no idea what was actually causing the problem, so I just went for "Plan B". Media Creation Tool probably would have worked just as well.

I didn't make the connection, but I too noticed a Defender update that kept appearing and then failing. "Plan B" works!

I did as you suggested and my laptop updated, also did the same to my desktop by pulling the cable from the back of my desktop and it is updating, so I think you have found a workable solution.

This is pretty similar to what happened to me...the repeating Defender definitions update would have stopped without the Internet connection.

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.

Thanks Unicore! Your fix worked perfect for me! :)

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

I used the MCT as well but did a complete clean install. I'm hoping that will solve some problems that still cropped up now and again such as the Start menu not responding, and the occasional network problems.

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 did the later, and I wonder if that's the source of the issue.

The Windows10Upgrade28084.exe failed twice for me. I suspect that something is wrong with it. One of the failures told me that my graphics card was not supported. I've been running Win for a year now on it. What worked for me was using the ISO to do an in place upgrade.

Thanks Unicore! YES. I ran the Windows 10 Upgrade Assistant Tool as well. After repeated failures, disconnecting the ethernet cable worked! Microsoft needs to come out with "Anniversary Update 1607.1" with a fix for everyone.

I disconnected my TV from the router and that fixed it for me.

THANK YOU Unicore. This worked perfectly for me. I really appreciate your post!
