You may have already heard that Microsoft named ‘Windows 10’ as their next operating system and successor to Windows 8/8.1.
 
Although the Redmond company didn’t revealed any reason for skipping Windows 9 name and jumping to Windows 10, but there are rumours that third-party apps could wrongly identify Windows 9 as 95, so the company skipped the Windows 9 name.
