Windows 11 22H2: Preview Update KB5029351 (August 22, 2023)

[German]Microsoft has released the optional cumulative (preview) update KB5029351 for Windows 11 version 22H2 as of August 22, 2023. This brings a number of fixes (similar to the preview update for Windows 11 21H2). Below I give an overview regarding these updates for Windows 11.

It should be noted that this update is a so-called preview update. This is optional and by default must be manually triggered to download and install (though Windows 11 22H2 includes options to install automatically). The update contains the fixes that will be rolled out in the security update for the following month. The list of updates for Windows 11 can be viewed on this Microsoft page.

Preview Update KB5029351 for Windows 11 22H2

The preview update KB5028254 has been released for Windows 11 version 22H2. The update raises the OS build to 22621.2215 and provides new features as well as fixes for this Windows version. Here is an overview of the highlights that the update brings:

• New! This update adds a new hover behavior to the search box gleam. When you hover over it, the search flyout box might appear. You can adjust this behavior by right-clicking the taskbar. Then choose Taskbar settings to change your search box experience.
• This update supports daylight saving time (DST) changes in Israel.
• This update addresses an issue that affects the search icon. When you select it, the Search app does not open. This occurs after a machine has been asleep.
• This update improves the reliability of the Search app.

• This update addresses an issue that affects Narrator. It does not correctly identify the search box on the taskbar and search highlights within the search box.

Below is the complete list of fixes that this update provides:

• New! This update adds new functionality that affects app defaults. To learn more, see A principled approach to app pinning and app defaults in Windows.
• New! This release adds a new policy called "Enable optional updates." Administrators can use it to configure the monthly, optional cumulative updates for commercial devices. You can also use this policy for the gradual Controlled Feature Rollouts (CFR). To learn more, see Enable and control optional updates for your organization.
• This update addresses an issue that affects the Group Policy Service. It will not wait for 30 seconds, which is the default wait time, for the network to be available. Because of this, policies are not correctly processed.
• This update adds a new API for D3D12 Independent Devices. You can use it to create multiple D3D12 devices on the same adapter. To learn more, see D3D12 Independent Devices.
• This update addresses an issue that affects a WS_EX_LAYERED window. The window might render with the wrong dimensions or at the wrong position. This occurs when you scale the display screen.

• This update addresses an issue that causes high CPU use. This occurs when you enable the "fBlockNonDomain" policy.
• This update addresses an issue that affects disk partitions. The system might stop working. This occurs after you delete a disk partition and add the space from the deleted partition to an existing BitLocker partition.

• This update addresses an issue that affects settings. They do not sync even if you turn on the toggle on the Windows Backup page in the Settings app.
• This update addresses an issue that affects the Resultant Set of Policy (RSOP). The Windows LAPS "BackupDirectory" policy setting was not being reported. This occurs when the setting is set to 1, which is "Back up to AAD."
• The update addresses an issue that affects those who use Windows Update for Business. After you are asked to change your password at sign in, the change operation fails. Then you cannot sign in. The error code is 0xc000006d.
• ange operation fails. Then you cannot sign in. The error code is 0xc000006d.

This long list of new features and fixes will be integrated in the security update for the following month. The preview update is optional and is only offered when the user explicitly selects optional updates for installation in the settings page. The update is offered via Windows Update, but can also be downloaded and installed from the Microsoft Update Catalog. The latest Servicing Stack Update (SSU) is included to fix various issues. Further details, e.g. about the installation requirements, can be found in the support article in case of doubt. The possibly known problems are also listed there.

Note: I can't track it directly anymore – since the same build is mentioned. But it looks to me as if Microsoft has amended the list of changes vigorously after I've published the 1st version of this blog post. I have therefore updated above the whole list of changes.
