Windows 12 to arrive in 2024.
First, insert cricket sound here./
Second, those guys can't be trusted. They said 5 years ago or so that Windows (10) was the last Windows version that would ship, and they used this ever since in order to force updates down the throat of every single licensed user on the planet (windows updates cannot be refused, they can only be pushed a couple days later). And yet, here we are with so-called "major" releases again.
Third, everyone knows that Microsoft can't ship anything without breaking features, drivers, etc. So IT Admins must scramble again at the idea that this will again have major deployment effects across the enterprise.
Last but not least, the bozos working at Redmond do not believe in their own shit, so they keep cancelling what they have introduced before. So expect changes to the user interface again...
All this while what the majority of Windows users want is a stable OS. A freaking S T A B L E OS and nothing else.
