Microsoft releases KB5009566 update to fix long-standing Windows 11 issue
Microsoft has released the first cumulative patch of 2022 for Windows 11 in the form of the KB5009566 update.
The patch is a mandatory cumulative update that addresses security problems thanks to the inclusion of January 2022 Patch Tuesday fixes. These address no fewer than six zero-day vulnerabilities, and a total of 97 security issues in all. The KB5009566 update also address a long-standing issue with Windows 11 and takes the operating system up to build 22000.434.
- Microsoft reveals 'powerdir' macOS vulnerability that allows unauthorized user data access
- Microsoft acknowledges that the KB5008212 update breaks Outlook search in Windows 10
- Microsoft releases emergency KB5010196 and KB5010215 updates to fix serious remote desktop problems in Windows Server
Microsoft says of the 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".
While people affected by this problem will be pleased to see that it has now been addressed, the K5009566 update has known issues of its own. Microsoft explains:
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.
This is something that the company has talked about before, and a fix is due to be released later this month.
