However, new functions are not included in the update. However, some optimizations have been made. Build 19645 removes the Linux kernel used by the Windows Subsystem for Linux (WSL2) from the Windows image.

Update contains numerous bug fixes
Windows 10 Build 19645 comes with a variety of bug fixes. Microsoft has fixed a problem with devices that boot from an eMMC memory. When waking up from hibernation, some users only got an error message. In addition, a bug was fixed that caused the preview icons in the taskbar to be rendered incorrectly.
In addition, the Windows Hello setup program should no longer crash if facial recognition has already been set up and the user has selected the “Improve recognition” option. The complete changelog can be found in the official blog entry of the Redmond company. Of course, there are still some problems in Windows 10 Build 19645. Microsoft is currently working on a bug that will cause the update process to freeze over a long period of time. The bug occurs in some cases as soon as the user wants to install a new preview version. In addition, the icons in some sub-items of the data protection settings of Windows 10 do not work correctly. A future insider build will fix this problem.
