Windows 10 KB5027293, with Build number 19045.3154, has finally arrived for Windows 11 version 22H2 users. 

Now live in the Release Preview channel, the update brings a range of improvements and enhancements to the operating system.

The update also adds support for Unicode Extensions E and F in the Simsun Ext-B font.

Several issues have been addressed in this update as well. It resolves problems with the on-screen keyboard failing to open after the machine is locked and ensures that scheduled monthly tasks run on time during daylight savings time changes. The update also prevents the deletion of registry settings under the Policies paths and improves the reliability of the Desktop Window Manager (DWM).
