The company said a preview of Windows 8.1 will be released next month.
Microsoft has made changes to Windows 8.1 operating system (OS), which include a return of a Start button.
The Start screen in Windows 8.1 features a variety of tile sizes including a new large and new small tile.
Microsoft said users can view all apps just by swiping from the bottom to view all apps, and it has also added the ability to filter apps by name, date installed, most used, or by category.
In Windows 8.1, the Search feature will aggregate results from different sources, including the web, apps, files, SkyDrive and actions users take.
The company said in Windows 8.1, users can save files directly to SkyDrive and the updated PC settings will give access to all settings on their device without having to go to the control panel on the desktop.
Microsoft corporate VP of windows programme management, Antoine Leblond, said: "We’ve improved the way you navigate to Start with the mouse by changing the Start "tip" to be the familiar Windows logo."
"The new tip appears anytime you move the mouse to the bottom left corner of the screen, and is always visible on the taskbar when on the desktop," Leblond added.
Microsoft said a preview of Windows 8.1 will be released in June this year.
