FIX: KB3176934 Fails to Install on Windows 10

Windows 10, which was introduced as a new concept with regular updates instead of new versions, hasn’t really been stable and consistent with its updates. For some users, for example, this became evident when they tried to install the KB3176934 update. This update was released on the 23rd of August, and contains minor improvements and fixes for the overall functionality of Windows 10 Version 1607.

Some users faced issues such as the update freezing at random percentages, or even going through, only to say that it failed after you restart your device in the end. This can be annoying as users who have committed to the latest version of Microsoft’s operating system have done so knowing that they will have timely updates that will fix any possible bugs and errors with the OS.


The solution for those that are unable to install the update is as simple as logging in as an admin. Follow the steps in the method below to be able to install the update.

Method 1: Use the Media Creation Tool by Microsoft

The Media Creation Tool is used for two purposes, one is to create bootable CD and USB for installing Windows on your computer, and the other is to upgrade your Windows 10 device to a newer build, as well as install any updates. Using it, you can install the update that is otherwise causing you a headache.

You can download Microsoft’s Media Creation Tool from its official website, and install it on your computer.

  1. If you get a UAC prompt, click Yes.
  2. Accept the license terms, and select Upgrade this PC now. Click Next.
  3. The latest build of Windows 10 will now download, so be patient. After that, it will start preparing.
  4. Once that is done, select the Download and install updates option, and click Next.
  5. Click Accept for the license terms once more.
  6. When Windows is done checking your device and files, click on Install to start the setup process.
  7. You will be given a choice of what to keep. If the only option is Nothing, the installation media you’re using is not the same one as the one you have installed. You’d be best off by selecting Keep personal files and apps, as that basically keeps everything intact.
  8. Windows will now start the upgrade to repair install Windows. Click Next when everything is ready.
  9. You now have a choice of either Express or Custom settings, so choose which one you want according to your needs.
  10. Click Next on the following screen, and you will be able to sign in to Windows. When you sign in for the first time, you will see an animation that you would normally get when you have done a clean install – don’t worry and let it work.
  11. At this point you’re running the latest update, and if you want, you have an option to use the built-in Disk Cleanup tool, and let it delete the Previous Windows installation(s), Windows Upgrade log files and Temporary Windows installation files. These files aren’t really necessary and they do take up a lot of space, so you can go ahead and delete them.


Method 2: Login as admin and install the update

Having a limited user account can lead to an inability to install software, as well as updates such as this one, and having administrator privileges solves this. However, not all users have such privileges, and some will need to enable that administrator account first. Fortunately, Windows 10 has a built-in elevated Administrator account you can use for such situations.

Option 1: Via an Elevated Command Prompt

  1. Press the Windows key on your keyboard, and type cmd  Right-click the result, and select Run as administrator to open an Elevated Command Prompt.
  2. Inside the Elevated Command Prompt, type the following command, and press Enter on your keyboard to execute it:

net user administrator /active:yes

  1. Close the command prompt, and sign out. You will have the option of logging in as an Administrator from the sign-in screen.

Option 2: Via the Local Users and Groups Manager

Note that this option is only available for users of the Pro and Enterprise editions of Windows 10.

  1. Press simultaneously the Windows and R keys on your keyboard to open the Run
  2. Type lusrmgr.msc, and either press Enter on your keyboard, or click OK to open the Local Users and Groups Manager.
  3. From the left navigation pane, click on the Users folder, and then double-click the Administrator account in the middle pane.
  4. To enable the account, uncheck the Account is disabled box, and click Apply, then OK to save the settings.
  5. Close the Local Users and Groups Manager, and sign out. You will see the Administrator account on the sign-in screen now.

Option 3: Via the Local Security Policy

Note that this option is also only available for users of the Pro and Enterprise editions of Windows 10, like the previous one.

  1. Open the Run dialog using step 1 of the previous method, and type secpol.msc, then open it.
  2. From the Local Security Policy window, expand the Local Policies and click on the Security Options in the left navigation pane.
  3. In the right pane, double click Accounts: Administrator account status.
  4. Select Enabled, and click Apply, then You can close the Local Security Policy, and log in with the Administrator account.

Whichever of the aforementioned methods you opted for, you should now be able to log in with the Administrator account of Windows 10. Run Windows Update again, by pressing the Windows key, typing Check for updates and opening the result, then clicking Check for updates. Windows 10 should now install the KB3176934 update without any problems. You might be required to reboot your device in the end – do so to save the changes, and you’ll be good to go.

It’s a well-known fact that a number of users haven’t yet updated to Microsoft’s latest and greatest, due to issues such as this one. However, there are solutions to the vast majority of issues that you might face with Windows 10, and if you follow the methods described above, you will have no problems getting it to run properly.
