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. |

You might have intermittent issues saving, copying, or attaching files using 32-bit apps, which are large address aware and using the CopyFile API. Windows devices are more likely to be affected by this issue when using some commercial or enterprise security software that uses extended file attributes. Microsoft Office apps, such as Microsoft Word or Microsoft Excel are only affected when using 32-bit versions and you might receive the error, "Document not saved." This issue is unlikely to be experienced by consumers using Windows devices in their home or on non-managed commercial devices. Apps are not affected by this issue if they are 64-bit or 32-bit and NOT large address aware. |
This issue is addressed in KB5027231. |
