Microsoft has released a new Windows 11 build with a long list of improvements and fixes for known issues for all Windows Insiders that will install the Windows 11 Insider Preview Build 22557, now available in the Dev Channel.

Probably the most awaited change is the revival of drag and drop support to the taskbar that allows Windows 11 users to drag and drop files between apps by hovering the mouse over their taskbar icons.
