Download Windows 10 KB5026435 Optional Non-Security Preview Update [May 2023]

It is the 4th Tuesday of the month, and this means that it is time for Microsoft to release the Type D optional non-security update for its supported Windows operating systems. Microsoft has published KB5026435 for Windows 10 22H2. This is an optional update, which means it will only install if you allow it manually.

If you opt not to install this update, most of the fixes and improvements included in this update will be applied automatically when the next month’s Patch Tuesday updates are installed. However, if you do install it, your operating system’s build will be upgraded to 19045.3031.

KB5026435 introduces minor features and improvements to the Windows 10 operating system. The highlights of this update are an improved search box experience in the taskbar, and displaying three high-priority toast notifications.

The following list of fixes and improvements have been implemented with this release:

• This update brings an improved search box experience on the taskbar. If you have a top, bottom, regular, or small icons taskbar, you will see the search box appear. You can use it to easily access apps, files, settings, and more from Windows and the web. You will also have access to the latest search updates, such as search highlights.
• This update now displays up to three high-priority toast notifications at the same time. This feature affects apps that use Windows OS notifications to send notices for calls, reminders, or alarms.

• This update addresses an issue that affects the Storage Spaces Direct (S2D) cluster. It might not come online. This occurs after a periodic password rollover. The error code is 1326.

• This update addresses an issue that affects signed Windows Defender Application Control (WDAC) policies. They are not applied to the Secure Kernel. This occurs when you enable Secure Boot.
• This update addresses an issue that might affect a large reparse point. You might get a stop error when you use NTFS to access it. This issue occurs after a canceled FSCTL Set operation changes the reparse tag.
• This update addresses a known issue that might affect some speech recognition apps. They might have sporadic speech recognition, expressive input, and handwriting issues. This occurs when the display language is Chinese or Japanese. The apps might not recognize certain words. They might not receive any input from speech recognition or affected input types. This issue is more likely to occur when the apps use offline speech recognition. For app developers,this issue only affects speech recognition that uses Speech Recognition Grammar Specification (SRGS) in Windows.Media.SpeechRecognition. This issue does not affect other types of speech recognition.

With these fixes and improvements to Windows 10, there are still also some known issues with this update.

Known Issues in KB5026435

Intermittent Issues while Saving, Copying, Attaching Files using 32-Bit Apps

There is an issue where 32-bit applications may not function as expected. Users may intermittently experience issues with such apps while trying to save them, copying them, or attacking them to other packages.

Devices that are being managed by enterprises are more likely to experience this problem. The 32-bit version of Microsoft Office applications might show the error “Document not saved” when attempting to save files in Word or Excel.

Note that not all 32-bit apps are affected, only the ones that are large address aware.

The only workaround right now, suggested by Microsoft, is to retry the same action that caused the error. Since this is an intermittent issue, it may likely be successful the next time you perform it.

If the problem is not resolved after multiple attempts, then the problem might be something else, but similar. If so, Microsoft suggests using the Known Issue Rollback (KIR) Group Policy, which can be downloaded from the link below:

Download Known Issue Rollback Group Policy for Windows 10

Note: The policy will need to be installed and configured according to your Windows version, which you can confirm by typing in winver in the Run Command box.

Missing Microsoft Edge

An issue with the standalone (clean) installation of Windows 10 with this update is causing Microsoft Edge Legacy to be removed. However, it is not being replaced by the new Chromium-based Edge.

This occurs only when Windows has a custom offline media or an ISO image installed that does not include the 29th March 2021 SSU update. Microsoft suggests that you either install the March SSU update through slipstreaming or simply update an existing OS through Windows Update, so you will not be facing this issue.

Alternatively, you can simply download and install the new Microsoft Edge if you have already encountered this problem.

Final Analysis

Microsoft changing its approach for releasing optional preview updates might just be a good thing. Previously, the end-users (us included) were uncertain when the next update may be released.

This will enable all of us to test out the new features and improvements anticipated in next month’s Patch Tuesday.
