==Internal version numbers== Software may have an "internal" version number which differs from the version number shown in the product name (and which typically follows version numbering rules more consistently). [[Java Platform, Standard Edition|Java SE]] 5.0, for example, has the internal version number of 1.5.0, and versions of Windows from NT 4 on have continued the standard numerical versions internally: Windows 2000 is [[Windows NT|NT]] 5.0, XP is Windows NT 5.1, [[Windows Server 2003]] and [[Windows XP Professional x64 Edition]] are NT 5.2, [[Windows Server 2008]] and Vista are NT 6.0, [[Windows Server 2008 R2]] and Windows 7 are NT 6.1, [[Windows Server 2012]] and [[Windows 8]] are NT 6.2, and [[Windows Server 2012 R2]] and [[Windows 8.1]] are NT 6.3. Windows 10 was initially intended to be NT 6.4, as the earliest Technical Preview build shared to the public is numbered 6.4.9841. However, that did not last as the version of Windows 10 was quickly artificially increased to 10.0<ref>{{Cite web |last=Tyrsina |first=Radu |date=2014-11-21 |title=Windows 10 NT kernel gets bumped from 6.4 to 10 in recent internal builds |url=https://windowsreport.com/windows-10-nt-kernel-gets-bumped-64-10-recent-internal-builds/ |access-date=2024-07-07 |website=Windows Report |language=en-US}}</ref> to align with the commercial name, resulting in the first released version of the operating system being numbered 10.0.10240. Note, however, that Windows NT is only on its fifth major revision, as its first release was numbered 3.1 (to match the then-current Windows release number) and the Windows 10 launching made a version leap from 6.3 to 10.0.
