Microsoft recently rolled out a new preview version of Windows 11 to members of the Windows Insider Program. This update was made available exclusively to users in the Canary Channel, which is the most experimental and unstable testing environment within the program. Updates in this channel often introduce early-stage features that may undergo significant changes before reaching the general public.
A major enhancement in this preview build is the improved speed of ZIP file decompression when using File Explorer’s built-in tool. This optimization is especially beneficial for users handling archives with a large number of smaller files, as the extraction process is now significantly faster. This improvement aims to enhance workflow efficiency for those who frequently work with compressed files.

Bug Fixes and Stability Improvements Enhance Multi-Monitor Support and System Performance
In addition to performance improvements, the update includes a variety of bug fixes designed to improve system stability. One particularly notable fix resolves a graphics issue experienced by users with multiple monitors, ensuring a smoother and more reliable display experience. These fixes highlight Microsoft’s commitment to refining Windows 11 based on user feedback.
