    Windows 11 is still garbage. How many years will it take them to bring back a productive operating system?

    It’s an absolute shame that after two years of long waiting Microsoft is still unable to release the lost features of the W11’s taskbar. Absolutely nonsense that currently dozens of third party software are able to turn back all the older enhancements of the W10’s taskbar in order to increase productivity. Two years of absence of any kind of intelligence by the side of the Windows 11 development team. Mostly all of my friends are stuck in W10 because they dislike a single thing like a taskbar, the worst idea of development that Microsoft has had in almost a decade since the perfect W7.
