Microsoft Releases Windows 10 Cumulative Updates KB4494441, KB4499167, KB4499179 

Microsoft has released a new series of cumulative updates for Windows 10 as the company rolls out its typical Patch Tuesday fixes.

 

Microsoft has released a new series of cumulative updates for Windows 10 as the company rolls out its typical Patch Tuesday fixes.

 

As usual, because they are shipped on a Patch Tuesday, these cumulative updates are first and foremost focused on resolving vulnerabilities in Windows 10, apps like Microsoft Edge and Internet Explorer, as well as other OS components.

All Windows 10 versions are getting cumulative updates this month, but the star of the show is obviously the October 2018 Update, or version 1809, which right now is the most recent stable version of Windows 10.

A new feature update is projected to go live later this month as May 2019 Update, or version 1903. For the time being, however, this update is still in the Release Preview ring of the Windows Insider program for last-minute testing before the public rollout. The RTM build was compiled in late April.

The May 2019 cumulative updates for Windows 10 are the following:

Windows 10 version 1809: May 14, 2019—KB4494441 (OS Build 17763.503)
Windows 10 version 1803: May 14, 2019—KB4499167 (OS Build 17134.765)
Windows 10 version 1709: May 14, 2019—KB4499179 (OS Build 16299.1146)
Windows 10 version 1703: May 14, 2019—KB4499181 (OS Build 15063.1805)


At the time of writing this article, it’s obviously too early to discuss whether these cumulative updates install correctly or not. However, we’ll continue to monitor the main feedback channels, as we do every month, and we’ll post updates should any users run into trouble when installing them.

You can check out the full changelogs of this month’s cumulative updates in the box after the jump and head over to Windows Update if you want to take the risks of installing them right away.

As always, I recommend you to create a backup for your Windows installation, just to be able to restore your device should something go wrong.

What’s New in Windows 10 Cumulative Update KB4494441 

The May 2019 Patch Tuesday rollout brings a new pack of cumulative updates for Windows 10, and the October 2018 Update, or version 1809, is getting its own release.

 

The May 2019 Patch Tuesday rollout brings a new pack of cumulative updates for Windows 10, and the October 2018 Update, or version 1809, is getting its own release.

 
Windows 10 October 2018 Update is the latest stable version of the operating system at this point, with its first successor projected to go live later this month.

The adoption of the October 2018 Update has so far increased rather slowly, so at this point it’s running on approximately 30 percent of all Windows 10 devices. In other words, there’s a chance some users might skip it entirely and move directly to the May 2019 Update coming in just a few weeks.

As for what’s new in cumulative update KB4494441 the focus is obviously on resolving security vulnerabilities in Windows 10, but also in Microsoft Edge, Internet Explorer, the Windows Scripting engine, and other modules. You can check out the full changelog in the box after the jump.The changelogBut as per Microsoft’s typical approach, non-security fixes are included as well, and these are more than welcome given the further refine the experience with the OS.

For example, cumulative update KB4494441 fixes a problem with certain fonts breaking down Microsoft Excel, while also introducing additional Spectre Variant 2 mitigations. Microsoft explains the following:

“Enables “Retpoline” by default if Spectre Variant 2 (CVE-2017-5715) is enabled. Make sure previous OS protections against the Spectre Variant 2 vulnerability are enabled using the registry settings described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions).”

While Microsoft recommends users to install this update as soon as possible, some might just want to wait given that cumulative updates have previously caused issues or failed to install. Right now, however, there are no reports of failed installs.

It remains to be seen how reliable this cumulative update truly is, so let us know in the comment box below should you run into any issues when installing it.

Windows 10 Cumulative Update KB4494441 Installing Twice for Some Users 

The most recent cumulative update for Windows 10 October 2018 Update, or version 1809, installs twice on some devices.

 

The most recent cumulative update for Windows 10 October 2018 Update, or version 1809, installs twice on some devices.

Windows 10 cumulative update KB4494441 was published as part of the May 2019 Patch Tuesday, bringing both security and non-security improvements to devices already updated to version 1809.

The update comes with four different known issues, all of them borrowed from the previous patches for Windows 10, but none of them pointing to any installation problems.

But as discussed in this reddit thread, Windows 10 cumulative update KB4494441 installs twice on a number of devices for a reason that’s yet to be determined.

By the looks of things, the behavior is the same in all cases. KB4494441 is first offered to Windows 10 October 2018 Update devices via Windows Update, with a reboot then required to complete the installation. Despite the machine being restarted, KB4494441 is then re-offered for a second time on Windows Update, once again with a reboot required to finalize the update.

After the second system restarted, KB4494441 appears to be installed correctly, with the OS build number increased to 17763.503. After the first install, the OS build numbers continues to be 17763.475.Bug acknowledgedMicrosoft has acknowledged the problem and says that “Windows 10, version 1809 Update Tuesday update may install twice,” adding that it is currently investigating and will provide an update when available.

Fortunately, the installation of cumulative update KB4494441 doesn’t seem to fail on any devices, so despite needing a second attempt to complete the install, everything appears to be working correctly.

To check if KB4494441 installed correctly on your device, click the Start menu and type winver to verify the OS build number. If you’re currently running 17763.503, everything worked well. Also, in the update history page, you should see the following entry:

2019-05 Cumulative Update for Windows 10 Version 1809 for x64-based Systems (KB4494441) (2) Successfully installed on [date]

Known Issues in Windows 10 Cumulative Updates KB4494441 and KB4499167 

Windows 10 users have been provided with new cumulative updates as part of the May 2019 Patch Tuesday cycle, but as it happens every month, the release includes not only fixes and security improvements, but also several known issues.

 

Windows 10 users have been provided with new cumulative updates as part of the May 2019 Patch Tuesday cycle, but as it happens every month, the release includes not only fixes and security improvements, but also several known issues.

Windows 10 October 2018 Update (version 1809) devices are offered cumulative update KB4494441, while those running Windows 10 April 2018 Update (version 1803) need to install update KB4499167.The known issuesFirst of all, let’s see what KB4494441could break down on your device. This update comes with four known issues listed on its official KB page (linked above), and all are borrowed from the previous cumulative updates.

The first bug causes issues with the Preboot Execution Environment (PXE) when starting a device from a Windows Deployment Services (WDS) services with Variable Window Extension.

Then, this update breaks down certain options, such as renaming, on files or folders stored on a Cluster Shared Volume (CSV), while the third bug makes printing from Microsoft Edge and other UWP apps to fail with error “Your printer has experienced an unexpected configuration problem. 0x80070007e.”

And last but not least, after installing this update you could end up unable to use some Asian language packs.

Earlier today, Microsoft also acknowledged a fourth bug that causes cumulative update KB4494441 to install twice on Windows 10 devices.

In the case of KB4499167, there are two such known issues that users might experience after installation.

The first one is the PXE issue detailed above, while the second is the same CSV bug that makes it impossible to run certain operations with files and folders, like renaming.

All these issues are supposed to be fixed “in an upcoming release,” as Microsoft itself puts it, albeit at this point there are no specifics on when you should expect a patch.

The installed version of my Windows is Windows 10 Enterprise Version 1809 Build 17763.475.

As per Microsoft the Latest Build is 17763.503, but I have not found any update using to Windows Update. I need to update to Version 1903. So what I have to do now? Is it dependent on product key?
