Windows Version Numbers
Below is a list of major Windows versions and their associated version numbers: [2] Windows XP Professional 64-bit had its own version number of 5.2. As far as we know, that’s the only time Microsoft has designated a special version number for a specific edition and architecture-type of a Windows operating system. [3] Service pack updates to Windows XP did update the build number but in a very minor and long-winded way. For example, Windows XP with SP3 and other small updates is listed as having a version number of 5.1 (Build 2600.xpsp_sp3_qfe.130704-0421 : Service Pack 3).
How to Update Windows
To update Windows to the newest build number, use Windows Update. The built-in Windows Update utility is the easiest way to check for and install Windows updates. If you haven’t set up your version of Windows to install updates automatically, you can change the Windows Update settings so that new updates are downloaded and applied automatically. It’s the simplest way to keep Windows updated to the latest version number.
Major Changes in Windows 10
Microsoft introduced several changes to the Windows operating system with Windows 10. These are some of the most significant differences between Windows 10 and Windows 8 (and older versions of Windows):
