Microsoft has released its first Windows 11 Patch Tuesday update (KB5009566) for 2022. The update addresses an error that caused text to appear out of order when using a Japanese IME. In addition, it brings a servicing stack update that brings quality improvements to ensure Microsoft updates can be received and installed on your machine without issue. There’s also an issue present that affects colour rendering in some image editing programs but Microsoft is working on a fix.

The only improvement and fixes in this update related to the Japanese IME error, in full Microsoft said this update:

  • Addresses a known issue that affects Japanese Input Method Editors (IME). When you use a Japanese IME to enter text, the text might appear out of order or the text cursor might move unexpectedly in apps that use the multibyte character set (MBCS). This issue affects the Microsoft Japanese IME and third-party Japanese IMEs.

As for the Windows 11 servicing stack update 22000.345, Microsoft said:

  • This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

The known issue and workaround in this update are as follows:

After installing Windows 11, some image editing programs might not render colors correctly on certain high dynamic range (HDR) displays. This is frequently observed with white colors, which could display in bright yellow or other colors.

This issue occurs when certain color-rendering Win32 APIs return unexpected information or errors under specific conditions. Not all color profile management programs are affected, and color profile options available in the Windows 11 Settings page, including Microsoft Color Control Panel, are expected to function correctly.

We are working on a resolution and estimate a solution will be available in late January.

To get the update, just open up Windows Update and keep applying any of the available updates and look out for KB5009566.
