See the last number shown in the version number column, like 7600 for Windows 7. Some sources note the build number in parenthesis, like 6.1 (7600). [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).
[4] At the end of 2022 a fully updated Windows 10 is essentially a super-version of Windows 11. Microsoft states of it’s own operating system Windows 11, “Some features in Windows 10 may no longer be available in Windows 11 after the upgrade.” In fact, Windows 11 is a scaled down version of Windows
10. Namely, Windows 11 ONLY works on the newer 64bit processor machines, while Windows 10 still supports older 32 bit machines and the 64bit machines as well.
Windows 11 system requirements:
- A compatible* 1 GHz or faster dual-core 64-bit processor from Intel, AMD, or Qualcomm
- 4GB of RAM – 8GB is preferred
- 64GB of drive storage space – yes, it can be installed on a thumb drive!
- UEFI Secure Boot supported and enabled
- A Trusted Platform Module (TPM), version 2.0
- A DirectX 12-compatible GPU with a WDDM 2.0 driver
- A 720p display larger than 9 inches in size (not particularly designed for phone or tablet use!)
- Installation requires a Microsoft account to complete.
*The processor requirement is the most restrictive; supported processors include 8th-generation and newer Intel Core processors as well as AMD Ryzen 2000-series processors and newer. These chips launched in late 2017 and early 2018. Older computers cannot officially run Windows 11, unlike Windows 10 that supported almost anything that could run Windows 7 or Windows 8.
