===Microsoft Windows=== The [[Microsoft Windows]] operating system was first labelled with standard version numbers for [[Windows 1.0]] through [[Windows 3.1x|Windows 3.11]]. After this Microsoft excluded the version number from the product name. For [[Windows 95]] (version 4.0), [[Windows 98]] (4.10) and [[Windows 2000]] (5.0), year of the release was included in the product title. After Windows 2000, Microsoft created the [[Windows Server]] family which continued the year-based style with a difference: For minor releases, Microsoft suffixed "R2" to the title, e.g., [[Windows Server 2008 R2]] (version 6.1). This style had remained consistent to this date. The client versions of Windows however did not adopt a consistent style. First, they received names with arbitrary alphanumeric suffixes as with [[Windows Me]] (4.90), [[Windows XP]] (5.1), and [[Windows Vista]] (6.0). Then, once again Microsoft adopted incremental numbers in the title, but this time, they were not versioning numbers; the version numbers of [[Windows 7]], [[Windows 8]] and [[Windows 8.1]] are respectively 6.1, 6.2 and 6.3. In [[Windows 10]], the version number leaped to 10.0<ref>{{cite web|title=Announcing Windows 10|work=Blogging Windows |date=September 30, 2014 |url=http://blogs.windows.com/bloggingwindows/2014/09/30/announcing-windows-10/}}</ref> and [[Windows 10 version history|subsequent updates to the OS]] only incremented build number and update build revision (UBR) number. The successor of Windows 10, [[Windows 11]], was released on October 5, 2021. Despite being named "11", the new Windows release didn't bump its major version number to 11. Instead, it stayed at the same version number of 10.0, used by Windows 10.<ref>{{cite web|title=Windows 11: A new era for the PC begins today|url=https://blogs.windows.com/windowsexperience/2021/10/04/windows-11-a-new-era-for-the-pc-begins-today/|date=Oct 4, 2021|website=Windows Blogs}}</ref>
