KB2919355 Won’t Install? Complete Windows 8.1 Fix Guide

If you are trying to install KB2919355 and it keeps failing, you are not alone. This Windows 8.1 update—commonly called Windows 8.1 Update 1—often fails with errors like 0x800f0922, 0x80070002, or 0xa0001.

The KB2919355 update is a critical system update released by Microsoft that improves Windows 8.1 performance, security, and compatibility. Unfortunately, corrupted Windows Update caches or missing prerequisite updates frequently cause the installation to fail.

In my experience troubleshooting Windows systems across the United States, Canada, the United Kingdom, Australia, and Europe, this update failure usually comes down to one of three issues: damaged update files, missing dependencies, or a broken Windows Update service.

In this guide, I will show you the exact steps to fix KB2919355 installation errors, including resetting the Windows Update cache, repairing system files with DISM (Deployment Imaging Service and Management Tool), and manually installing the update package.

Properly executing the Windows 8.1 update is crucial to resolving the KB2919355 error. First of all, you have to make use of the Windows 8.1 update offline installer. Then click the Download button. There are multiple files that download during this process.

But you have to make sure they are installed in the right order. These KBs, or Knowledge Base articles, must be installed in the following path: clearcompressionflag. exe, KB2919355, KB2932046, KB2959977, KB2937592, KB2938439, and KB2934018.

But another prerequisite is that KB2919442 should be installed first before you attempt to install KB2919355.

KB2919355 Won’t Install? Fix All Errors in 3 Steps—Windows 8.1

Quick Fix: KB2919355 Installation Failure

Quick Fix: KB2919355 fails because of a corrupted Windows Update cache.

Fix:

1. Run this command in Administrator Command. Prompt

DISM /Online /Cleanup-Image /RestoreHealth

2. Stop Windows Update service and delete contents of

C:\Windows\SoftwareDistribution\Download

3. Restart the computer and retry the update.

This simple process fixes most KB2919355 update errors.

The same thing applies to the Windows Server 2012 R2 Update for fixing KB2919355.

The KB files you download are the same, but they differ in size for x64-based systems. The order of installation for the KB files and the previous KB remains unchanged.

Is KB2919355 required for Windows 10?

You must have upgraded from 8 or 8.1 to Win 10. If you have installed this software—Belarc Advisor—it will display a notification that KB2919355 is required as part of its analysis.

The solution to this problem is that you don’t install this update at all. But people who have installed the above software need to uninstall it. Then you download the latest version and update it. Restarting the computer resolves the issue. This procedure will stop any warnings about the KB2919355 error, which is a specific update issue related to Windows 10.

We recently talked about the Windows 8.1 Update 1 and its exciting features. But after April 8th, when I tried to download the update, I received an error. Though there are other updates related to Office 2013 that installed perfectly, one update, KB2919355, downloaded successfully but failed to install.

If you have “Windows Update” set to automatically check for updates, you should have received this update. The size is 700 MB approximately. You can manually check by going to the Start Screen and typing “Windows Update.”

But occasionally, it takes a lot of time to download this way, especially if the internet connection is slow or if the servers are busy. So I used this link from extremetech to manually download the updates.

There are actually 6 updates associated with Windows 8.1 Update 1.

1. KB2919442
2. KB291935
3. KB2932046
4. KB2937592
5. KB2938439
6. KB2934018

These updates have to be installed in a specific order. So KB2919355 comes as the second option. Since it failed, I installed the components randomly.

Update 2—The Ultimate Solution (Fixed on 27th April, 2014)

Eureka, I finally solved this piece of the puzzle after a lot of research and hard work. I got KB2919355 installed after some hectic forum searching and reading a lot of online material. The trick worked (I think) when I uninstalled some third-party software like Pokki, BlueStacks, and Pixsta and also did some other things.

The best solution when you fail to install the KB2919355 update is to temporarily block your internet connection, stop your antivirus (whether it’s Windows Defender or KAV 2014), and also run the below script (run as administrator). But before you do that, first download the manual installer for this update.

Windows 8.1 Fix for Update

After it installs, you need to reboot so the new changes are visible. I really got a hint from an article by @Anand Khanse, which helped me in the right direction.

If this update doesn’t install, you can try these suggestions and see if they help you. Before starting, consider uninstalling third-party customization software, reversing any system changes like moving user files or profiles, and temporarily disabling your security software.

As you can observe, these are the golden works to solve your problem. I was given an error code of 0x80070005 during the error resolution process. The above changes also rectified the issue.

Update 1:

I recently attempted to use the latest offline installer from Microsoft’s download page, which received an update on April 16th, 2014. Since the earlier Update 1 release was on April 8th, this updated version could work for some people. Furthermore, on some forums, I noticed that Microsoft rectified some of the errors in this latest manual installer.

Personally I tried to run a few commands like DISM and SFC, but that didn’t work out for me. Additionally, the latest installer failed at the final stages, just like the earlier ones, and displayed the same error screens.

First of all, the update took a long time to install.

Then it displayed a simple, annoying message that “some updates were not installed.”

How did I go about troubleshooting the KB2919355 update error?

I thought the issue was a simple cache problem, so I thought of cleaning all the temporary files and other system caches. So I used CCleaner to clean the registry and unnecessary files. I also cleaned the registry using the “Registry Cleaner” present in it.

That didn’t solve my problem.

The writer of the post, in a similar fashion, tried to troubleshoot the error and landed at a solution. First of all, if any installation fails, it’s better to check your Event Viewer.

How to Open Event Viewer in Windows 8.1?

Just type “Administrative Tools” by searching through the Charms bar or typing it directly from the Start screen. A little playing around will land you in Event Viewer.

By navigating to this option —> Custom Views > Administrative Events, you should find the culprit or the root cause for the KB2919355 Update error.

As you can see above, the error in my case was 0x80073712. The result was slightly different from the error obtained in my friend’s case. So this time I tried this error code in Google and found a solution in the form of this support article from Microsoft.

• KB2919355 update fail – Error 80073712
• Windows 8.1 update to 8.1B fails with error code 0x80073712

The Solution

This support article provides the solution for this error code. The Component-Based Servicing (CBS) manifest’s corruption is the primary cause of this error in Windows 8. 

When you try to install updates or components in Windows 8, Windows 7, or Windows Vista, you may experience one or more of the following symptoms:

• When you try to install an update using the Windows Update website, you may get an error message that includes the error code: 0x80073712, and the update does not install.
• When you click Turn Windows features on or off in the Programs and Features item in Control Panel, no features are displayed in the Windows Features dialog box.

The article provides 3 solutions.

1. Use a FIX-IT kind of code.
2. Use some command-line tools to clean up the image.
3. Refresh your PC

I was ecstatic that I got an answer. But later these solutions didn’t work out. When I ran the fix-it solution, this was the result.

The above screenshot shows that the recent update installation issues remain unresolved. Furthermore, there was a warning message for missing or corrupt files. The other checks,

• Service registration is missing or corrupt
• Windows Update error 0x80073712

were fixed.

The next resort was to check the earlier post, which guided me in some direction. Then reluctantly I checked the CBS.log present at this location.

C:\WindowsLogsCBSCBS.log

I also had doubts that my Windows 8.1 was not genuine, which may have caused the error. But until now, all the updates have installed successfully, so why was this update not installing correctly? So I went into it with more madness!

Though I got a hint of the problem from this log, I thought that my limited knowledge and lesser debugging skills were making it a headache to solve.

So I stopped at this stage and did not go further into the intricacies of the KB2919355 update error.
