Windows Cumulative Update not installing or fails to install

At times, you may find that the Windows Cumulative Update is not installing or fails to install. This may happen on your Windows 10 or Windows 8.1 PC. In this post we have taken the example of the KB2919355 package for Windows 8.1. But this process is indicative and can be used for other cumulative update packages for Windows 10 as well, by making appropriate changes. In this post, we will see some generic and specific ways to try and troubleshoot this problem.

Windows Cumulative Update not installing

First, you need to note down the error code which is shown during the failed installation. Most have been reporting error codes 0x80070020, 0x80073712, 0x80070002, 0x80070003, 0x800F0923, 0x800F0922 and 0x800f081f to Microsoft.

Additional information about Error Code 0x80070020 is as follows:

Dec Error Code: -2147024864


Error Description: The process cannot access the file because it is being used by another process

Windows Update errors 0x80070020, 0x80073712, 0x80070002, 0x80070003, 0x800F0923, 0x800F0922, 0x800f081

Windows 8.1 Update is shown as Important when you open Windows Update, yet it is unchecked by default. You have to check it in order to install it. Moreover, if you are on a metered network, Windows 8.1 Update will not install automatically even if you have Automatic Update turned on. You will have to connect to an un-metered connection or public Wi-Fi connection to install the update.

If this update does not install, you can try these suggestions and see if they help you. But before you begin, it might be a good idea to uninstall any third-party customization software you may have installed, reverse any system changes you may have made – like relocating your user files or user profiles to another drive and disable your security software, temporarily.

Windows 8.1 Update will not install automatically on metered networks. If you have Automatic Update turned on and are on metered connections you may see a notification Windows Update couldn’t install the updates automatically. It is recommended that you connect to an un-metered connection or public Wi-Fi connection and then check for and install the Windows 8.1 Update.

Also ensure that the Servicing Stack KB2919442 is installed on your computer, as it is a prerequisite for Windows 8.1 Update. It should therefore first be installed on your system before your attempt to install Windows 8.1 Update or KB2919355. Go get it here if your computer does not have it.

1] If your Windows 8.1 Update has failed to install, you need to clean up the corrupted installation. To do this, you can make use of the built-in Deployment Image Servicing & Management or DISM.exe tool.

Open command prompt as administrator, type the following and hit Enter:

Dism /Online /Get-Packages

You will get a list of packages. Since KB2919355 has not been successfully installed on your computer, you won’t see it, but you can see it installed on my 64-bit system.

Windows Cumulative Update not installing

If you do see it, then it may mean that it has been installed or that the installation is corrupted. In this case, see if you can uninstall it via the Control Panel > Installed Updates. If you cant, then proceed.

What you need to do now is type the following and hit Enter.

DISM /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~

This was for a 64-bit version of Windows.

For 32-bit Windows 8 use packagename:Package_for_KB2919355~31bf3856ad364e35~x86~~

For Windows RT, use packagename:Package_for_KB2919355~31bf3856ad364e35~arm~~

Next, type the following and hit Enter:

DISM /online /cleanup-image /startcomponentcleanup

You can read more what StartComponentCleanup does, in this post titled WinSxS folder cleanup.

You could also run the following:

DISM /online /cleanup-Image /restorehealth

/RestoreHealth checks for component store corruption, records the corruption to C:\Windows\Logs\CBS\CBS.log and FIXES the corruption using Windows Update.  This operation takes 15 minutes or more depending on the level of corruption. More on this at the post titled Windows Component Store Corrupt.

Restart the computer and try again.

But if think that your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or the Windows DVD, as the source of the files. To do this, run the following command instead:

DISM /online /cleanup-image /restorehealth /Source:C:\RepairSource\Windows /LimitAccess

Here replace C:\RepairSource\Windows with the location of your repair source.

2] KB2939087 recommends in case you are unable to install the Windows 8.1 Update package KB2919355 via Windows Update, then you should download and install the package manually.

3] If you receive Error 0x80071a91 when installing KB2919355 on Windows 8.1, Microsoft has released a patch to fix this issue. Go get it at KB2939087.

4] If you have any VPN client software installed, uninstall it, in case you receive Error 8000F0922. Removing the VPN helped solve the problem.

5] If you are unable to uninstall IIS after you install KB2919355 on Windows 8.1 or Windows Server 2012 R2, download and install the patch from KB2957390.

6] If you receive Error 0x80071a91 when installing update KB2919355 in Windows see KB2956283.

7] Earlier, after you installed this update on a computer, the computer could stop scanning against Windows Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2 or WSUS 3.2)-based servers that were configured to use HTTPS and do not have TLS 1.2 enabled. This issue was resolved in the latest version of this update that is released on April 15, 2014. If you still face this issue, see KB2959977.

8] You may check some of these generic troubleshooting steps that are known to help resolve Windows Update fail to install issues. Run the updated Windows Update Troubleshooter. This post also includes a link that allows you to search for Error Codes and their meanings.

9] Refresh your Windows and then try to install it. The chances of success will be very high.

Hope something helps!
