What’s new in the Windows 11 KB5026372
After installing today’s KB5026372 update, Windows 11 22H2 will have its build number changed to 22621.1635.
Microsoft made twenty changes in the Windows 11 22H2 KB5026372 update, with the highlighted ones listed below:
- This update fixes a race condition in the Windows Local Administrator Password Solution (LAPS), which causes the Local Security Authority Subsystem Service (LSASS) to become unresponsive. The LSASS stops responding due to the simultaneous processing of multiple local account operations, resulting in an access violation error code of 0xc0000005.
- Microsoft animated some of the icons for Widgets in the taskbar. For example, you will notice a new animation when a new announcement appears.
- Microsoft added a new toggle control on the Windows Update settings page. When turned on, Microsoft will prioritize the devices to get the latest non-security updates and enhancements when they are available.
- Microsoft Edge will now correctly display pop-up windows in the foreground rather than 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 taskbar live thumbnail previews.
Microsoft has also added more drivers to the database of drivers not compatible with the Kernel-mode Hardware-enforced Stack Protection security feature after Windows users reported problems.
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 no longer work or Windows 11 would crash unexpectedly due to conflicts with installed drivers.
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 Kernel-mode Hardware-enforced Stack Protection feature from being enabled.
Microsoft is aware of two ongoing issues for Windows 11 22H2 that have not been resolved in this update.
These are issues causing provisioning packages not to work as expected and a bug causing some apps to have intermittent problems with speech recognition, expressive input, and handwriting when using Chinese or Japanese languages.
