What’s new in Windows 11 KB5026372

After installing today KB5026372 update, Windows 11 22H2 will have its build number changed to 22621.1635.

Microsoft has made twenty changes in Windows 11 22H2 KB5026372 update, with the highlights listed below:

• This update fixes a race condition in the Windows Local Administrator Password Solution (LAPS), which causes the Local Security Authority Subsystem (LSASS) service to stop responding. The LSASS stops responding due to concurrent processing of multiple local account operations, resulting in an access violation error code of 0xc0000005.

• Microsoft has animated some of the widget icons in the taskbar. For example, you will notice a new animation when a new ad appears.

• Microsoft has added a new toggle control to the Windows Update settings page. When enabled, Microsoft prioritizes devices to get the latest non-security updates and improvements when they become available.

• Microsoft Edge will now correctly display pop-ups in the foreground rather than in the background when using IE mode.

• Fixed a Chinese input method issue that prevented Windows users from seeing suggested items.

• Protected content will no longer be visible in live thumbnail previews on the taskbar.

Microsoft has also added more drivers to the database of drivers not compatible with the Kernel-mode hardware-enhanced stack protection security feature after Windows users reported issues.

Last month, a Microsoft Defender update suddenly added a new security feature to Windows 11 22H2 devices without any information on how it works.

However, some users who enabled the feature found that their programs would stop working or Windows 11 would crash unexpectedly due to conflicts with the drivers installed.

Many of these conflicts involved game-related drivers, such as those for DRM and anti-cheat platforms.

Microsoft has added additional drivers that, if installed, will prevent the hardware-enhanced stack protection feature from being enabled in kernel mode.

Microsoft is aware of two ongoing issues for Windows 11 22H2 that have not been resolved in this update.

These are problems that cause provisioning packages not working as expected and a bug causing some apps to have intermittent problems with speech recognition, expressive typing, and handwriting when using Chinese or Japanese languages.
