The Windows 10 Anniversary Update is finally here. Windows users can’t wait to download it on their machines and test out the new features, but unfortunately not all of them have been able to install the Anniversary Update.

Before searching for a fix, bear in mind that the Windows 10 Anniversary Update rolls out in waves, and it may not be available for all users at the same time. Secondly, Windows 10 currently runs on more than 350 million devices worldwide, and rolling out the update to all these devices is quite an effort for Microsoft.

Thirdly, no piece of technology is bug-free. For various reasons, sometimes even the most reliable and stable operating systems and devices fail to work properly.

Users complain about failed Anniversary Update installs

The Windows 10 Anniversary Update is no exception to the rule, and many users have already reported issues when trying to install the update. Windows developers have been the first to encounter installation fails.

1. Hyper-V VM issues with version 1607

Ok so I’ve downloaded the Windows 10 Enterprise Anniversary ISO from the Microsoft Partner Site.

I’ve spun up a Hyper-V VM to install it.

Great, just after the customize settings screen I get this [error], and it wont go any further. […]

I’ve managed to get it past this on VMWare by disabling all Video Acceleration.

Now to figure out Hyper-V.

2. Users reported they couldn’t complete the Anniversary Update installation, claiming problems with restore and stuck downloads.

Soooo it downloaded and went through most of the install process, but on the final restart is said “restoring previous version of Windows” and then when it finally booted the OS it still says the update is still available… So I guess I’ll try again.

3. 0xa0000400, 0x80070057 errors encountered by early Windows 10 1607 users

Other users even encountered specific error codes, such as 0x80070057 and 0xa0000400 which stopped them from installing the Anniversary Update:

I’m getting the error 0x80070057 while trying to update. None of the solutions on web seem to work. I know several people that are having the same problem. What would be the solution?

4. When Windows 10 tries to update, it gets to a particular percentage and then fails with the 0x80070005 error

I’m trying to install the Anniversary Update for version 10. My current version is 1511 (10586 494). It downloads fine, the file has no errors, but when it tries to update, it gets to 2% then fails with the 0x80070005 error.[…]

Any clues? I know the above error means Access Denied, but what can’t it access? Is there a log file that I can look at?

5. The Anniversary Update restores the previous Windows version

I have not been able to update my SB to the Anniversary Upgrade. Every time it fails at some point and reboots with a message “Restoring Your Previous Version of Windows” without giving any sort of error message.

Finally I resorted to the Media Creation Tool which also failed in the same way.

6. Anniversay Update installation fails in the FIRST_BOOT phase with the 0C1900101 – 0x3000D error

My 1607 RTM upgrade was not successful. 0C1900101 – 0x3000D, installation failed in the FIRST_BOOT phase with an error during MIGRATE_DATA

I ran the Update Troubleshooter for 10, and got no issues.  I also tried using Task Manager to disable all Startup programs.  Not sure what to do about it.  Does this mean a clean installation is the only option?

7. The kmode_exception_not_handled error blocks users from installing the Windows 10 Anniversary Update

Anniversary Update fails to install kmode_exception_not_handled

I am getting this kmode_exception_not_handled after 70% install and restore to previous version of Windows 10 Pro.

If you’re getting this particular error, you can check out our dedicated fix article to solve this issue.

8. The Anniversary Update displays a blue window, informing users about possible incompatibility issues

“Sorry, we’re having trouble determining if your PC can run Windows 10. Please close setup and try again.”

But my PC is already running Windows 10. How do I work around this?

9. Windows 10 Anniversary Update fails to install with error 0x80004005

Tried 3 times with windows update and 2 times with the windows update assistant from the Microsoft site.  Windows update failed 3 times and the update assistant failed twice with error code 0x80004005.

10. Windows 10 Anniversary Update freezes midway through installation

The percentage completion gradually increased to 82% over an hour or so.  It now has been at 82% for about 6 hours.  There’s minimal hard disk activity now.  What can I do to get out of this frozen update process.

By now, the Anniversary Update should already be visible for most users, so if you still encounter errors when trying to automatically install the update, follow the steps listed below to fix this issue.

  • I tried to install Windows Anniversary Update on my Lenovo G510 Laptop when it arrived about two months ago about 3 times with the same result.
    Got stuck at 71 % and never proceeded further. After the 3 times of hard booting by forcefully shutting down the system, and recovery to the previous version….
    Now it says “The Update is not compatible” Error which is nuisance.
    I’ll be grateful to anybody who can help.
    Thank you https://uploads.disquscdn.com/images/baae285500f0c08e3253a6c4a6acefea1c9ce114cab21fccef362de3918f0fb1.jpg

  • Yes, this worked for me too. I unplugged the Logitech mouse USB and it worked. I had tried this install so many times and the solution was so simple. UNPLUG the USB.

  • Like reply #11 I had been trying everything above with the same result. It would get to about 75% on the install and then hang up. Since I was going to bed for the night I decided to try the USB fix. I have a wireless Logitech mouse and keyboard. I set the computer to restart about 15 minutes later, unplugged the USB plug from the computer, and went to bed. When I got up I plugged the USB connector back in, hit the power button to wake the computer up, and discovered the update had installed and everything was working fine. I had spent the previous afternoon checking all of the drivers for updates and had about 10 of them update. All the others said they were good. I tried to install the update again but I still had the same result as before. I checked the date on the keyboard driver and it said 2006. I guess they hadn’t put out anything newer. What a simple fix. I guess I need a later model keyboard and mouse.

  • I fell into reason 10 above. Followed all the steps above and it still failed. Also did all of these steps

    After this last fail I got a different error message did a search on it I found the same o stuff I’d already done. Last link I clicked same complaint and 1 reply there that said unplug any wireless usb plugs. I looked down and the computer I was working on had a logitech usb. Pulled and tried update again and holy crap it WORKED!

  • Hi I was having problems installing the new anniversary update so I tried the above steps word for word. The result was exactly the same; the update downloads, installs and then on the last restart there’s just a black screen with the white dot-wheel at the bottom. I’ve left this for around 2 hours but in the end I have to unplug and restart. It restarts and says it’s trying to recover the installation but then freezes again. After unplugging for a 2nd time it restarts and reverts back to the previous Windows version. According to the log, my pc has been starting up automatically at 3.30 am for the past week to do the install but it has failed every time. Anyone got other suggestions without installing reg cleaners etc?

  • Make sure to remove any windows.old folder before you try to update to windows 10 anniversary. I tried several times on my laptop getting to 99.99% complete, when it failed. After deleting the windows.old folder still there from the November 2015 update it installed like it should.

  • I have Win7/Win 10 dual boot system. All the updates so far has been a success but the anniversary upgrade fails. It looks like its trying to write something to the duaboot systems boot sector.
    How to fix?

  • can’t creat files. please check if you have permision to write installation folder

    got this eror when try to instal windows 10 Anniversary update

  • Having issues installing Windows 10 1607 on a Hyper V Server 2008 R2 Host.

    Looking at the event viewer logs this could be the issue.

    Device ‘Microsoft Synthetic Display Controller’ in ‘TESTMACHINE’ is loaded but has a different version from the server. Server version 3.0 Client version 3.5 (Virtual machine ID 6C2F809F-69A0-4FED-A099-B1F64C57AD79). The device will work, but this is an unsupported configuration. This means that technical support will not be provided until this problem is resolved. To fix this problem, upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.

  • I have a Dual Boot with Ubuntu, and while I am updating, and when the PC restarts automatically while I update, instead of giving me an option to open the Windows Launcher, Ubuntu directly boots up, after which I have to click restart in Ubuntu and then it gives me the option to open the Windows Launcher to continue the update.
    Also, my update after 75% just showed “Restoring Your Previous Version of Windows” without giving any sort of error message, and I am now doing the sfc/ scannow thing in the Command Prompt. Hopefully something works out 😛

  • I wouldn’t be too surprised if some of these issues are caused by people using Driver Cleaner software that is deleting the default drivers that come with Windows (Or registry cleaning software that is deleting important registry stuff). Windows uses these drivers for the Windows Setup during a system upgrade.
