Windows 11 is coming

On June 3, Microsoft sent a Tweet saying “Join us June 24th at 11 am ET for the #MicrosoftEvent to see what’s next.” Many insiders predict the event is the debut of the next generation of Windows – Windows 11, and it turns out to be true. Let’s have a quick peek at the big changes coming with Windows 11:

  • Start menu: the new Start menu lies at the center of your taskbar. If needed, you can move them all back to the left-hand side. 
  • File Explorer: some folder icons are updated. Besides, if you hover your mouse over the "maximize windows" icon, you'll see an option to align your window in a variety of configurations. 
  • Widgets drawer: Right in the middle of the Taskbar icons is Widgets. Instead of desktop widgets, it shows nothing more than News & Interests at the moment.
