Windows 11 servicing stack update - 22621.1626

All users	After installing this update, some apps might have intermittent issues with speech recognition, expressive input, and handwriting when using Chinese or Japanese languages. Affected apps might sometimes fail to recognize certain words or might be unable to receive any input from speech recognition or affected input types. This issue is more likely to occur when apps are using offline speech recognition. Note for app developers This issue only affects speech recognition using Speech Recognition Grammar Specification (SRGS) in Windows.Media.SpeechRecognition. Other implementations of speech recognition are not affected.	This issue is addressed in KB5026446.

How to get this update

Before installing this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Install this update

Release Channel	Available	Next Step

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
