Microsoft has released new preview versions in the Windows Insider channels, focusing on refining the taskbar in Windows 11. The latest Insider Preview versions include a new option called “Taskbar size” in the “Experimental” release channel (Build 26300.8758), with early screenshots indicating a default setting of “Small.” Users can also dock the taskbar on any side of the monitor. Improvements to system sounds in dark mode and more reliable thumbnail previews for cloud files in File Explorer's preview panel are also included in the Beta Preview (Build 26220.8754). Microsoft has restructured the Insider Preview Program, reducing it from four channels to two: Experimental and Beta, with the Release Preview channel remaining. Switching between Insider Preview channels has been simplified, allowing users to change channels more flexibly.
