[German]Microsoft has released an optional cumulative (preview) update KB5026435 for Windows 10 22H2 on May 23, 2023 (C-Week). This is supposed to fix numerous bugs in Windows 10 22H2. Below I provide an overview regarding these updates for Windows 10. The information about the updates can be found in the Windows 10 update history page.

It should be noted that these updates are so-called preview or preview updates. These are optional and must be manually triggered for download and installation by default. After March 2023, there will be no optional, non-security preview updates for supported editions of Windows 10, version 20H2 and Windows 10, version 21H2. Only cumulative monthly security updates (known as a "B" or Update Tuesday release) will continue for these versions. Windows 10, version 22H2 will continue to receive security and optional releases.
