Windows Insiders are receiving an update with Windows 11 build 28020.1371, which addresses a 'flash bang' effect in dark mode that has been troubling users, particularly on large OLED monitors. The update resolves an issue causing File Explorer to show a white flash when navigating between pages. It also introduces features such as Bluetooth LE audio support for two pairs of headphones and an internet speed check from the taskbar. Additionally, the Copilot app has been updated to version 1.25095.161. There are discussions about the reluctance of Windows 10 users to upgrade to Windows 11 due to stringent system requirements, although tools like Rufus allow some to bypass these limitations.
