What are some of Windows 11’s new features?

Windows 11 comes with a bound of new features which make its storage size larger than that of the subsequent Windows OS. The features on Windows 11 include:

  • Newly designed Start menu and taskbar

The most obvious difference between Windows 10 and Windows 11 is the Start menu. On the former, the Start menu is anchored to the left-hand bottom of the screen but this has been changed with the latter. 

Moreover, the Start menu has been moved to the center of the screen, just above the taskbar, which has also been redesigned to be at the center of the screen. However, Windows 11 only lets you pin the taskbar at the bottom of your screen.

  • Multitasking features for developers and gamers mostly

Multitasking was added to Windows 11 to allow users to run many applications at the same time to increase productivity.

Also, do not hesitate to check out some gaming settings that you need to enable in order to ensure top graphics performance.

  • Widgets that can be easily customized

As mentioned earlier, Windows 11 was created to better explore Windows OS on your PC. Most of the changes made are just an upgrade of what was on Windows 10.

On the Windows 11 taskbar, there is an option for Widget which shows a large panel of updates on weather, news, sport, and a lot more. Each of the widgets can be easily customized or even removed depending on the user’s discretion.

However, since the feature takes up a lot of space on the screen, you may choose to disable widgets in Windows 11.

What are Windows 11’s space requirements?
