New in Windows 10 build 19559
Improvements and bug fixes
Fixed a problem with the candidate window in the input method editor for East Asian IME (Simplified Chinese, Traditional Chinese, and Japanese), which sometimes did not open in recent builds.
Fixed an issue that could cause the explorer.exe process to crash when backing up folders containing .heic or RAW files.
Fixed an issue that could cause the explorer.exe process to freeze when trying to delete certain large .tif files.
Fixed an issue where several top pixels of a window were cropped when using the WIN + Up combination, and then snapped to the window using the WIN + Left / Right combination).
The problem that caused the crash of viewing events when selecting some events recently has been fixed.
Any insider using an ARM64 device, such as Surface Pro X, and running Windows 10 Enterprise or Pro, will now be able to install Hyper-V features.
Fixed an issue that caused some insiders in recent builds to have a green screen with a KMODE EXCEPTION NOT HANDLED error.
BattlEye and Microsoft have discovered incompatibility issues between some Insider Preview builds and certain versions of the BattlEye anti-cheat code. To protect insiders who may have these versions installed, they will be limited to upgrading to some Windows Insider Preview builds.
Narrator and NVDA users looking for the latest Chromium-based Microsoft Edge may have some difficulty navigating and reading certain web content.
The problem reports with the update process that has been hanging for a long period of time when trying to install a new assembly are examined.
Some insiders cannot upgrade to newer builds with error 0x8007042b or 0xc1900101.
The input method editor for East Asia (simplified Chinese, traditional Chinese, Korean, and Japanese) may not have a language / keyboard switch (for example, when you press the Windows key + spacebar) after upgrading from 20H1 Build 19041 or earlier to Windows 10 Insider Preview build (19536 or later) if multiple languages / keyboards are added. As a workaround, remove and re-add all the keyboards that are not in the keyboard switcher by going to Settings> Time and Language> Language> Preferred Languages. This will not happen if you upgrade to build19536 or later.
The “Documents” section in the “Privacy” section has an incorrect icon (just a rectangle).
Some devices go into standby mode more. If you encounter this problem, you can put the computer into sleep mode manually from the Start menu.
Some insiders encounter an error message when using WSL2: “A connection attempt failed on Windows 19555.1001”. A fix will be included in an upcoming release.
There is a problem in this assembly in which if you open the clipboard history (WIN + V) and close it without pasting anything, the input will stop working in many places until you restart the computer.
