The latest version of Windows 10 is November 2021 Update or 21H2, build 19044, and it was released starting November 16th, 2021. This version doesn’t introduce as many new features as previous ones. Still, it does keep the evolution process of Windows 10 alive and kicking. If you want to know whether you have the latest version of Windows 10 installed and how to check what version, build, or type of Windows 10 you’re using, read this guide:
This method is fast and works the same, no matter what version of Windows 10 you have: use the search box next to the Start button, type winver and click or tap the search result with the same name.
Alternatively, press the Windows + R keys to bring up the Run window, type winver, and press Enter or click or tap OK.
This command opens About Windows, where you see the Windows 10 version followed by the OS Build and the Windows 10 edition. For example, here is a PC with Windows 10 Pro and the November 2021 Update.
Is all this data confusing? Continue reading this tutorial to make sense of the version numbers that you see, the OS Build, the Windows 10 edition that you have, and so on.
This method works in all versions and editions of Windows 10, but things can look different, depending on the specific build you’re using. First, open the Settings app (the quickest way is to press Windows + I on the keyboard). Then, click or tap System.
On the left, scroll to the bottom and choose About. On the right, you see information about your system. The amount of information shown differs depending on the Windows 10 version you have installed. On the right, you see the lines with the data that interests you:
- System type - it tells you whether you use a 32-bit or 64-bit version of Windows 10
- Edition - it shares the edition of Windows 10 that you have: Pro, Home, Enterprise, Education, etc.
- Version - displays the version of Windows 10 currently installed
- OS Build - see the Windows 10 build number you’re using
These lines of information are positioned differently, depending on your version of Windows 10. For example, here is how the About section looks in the Windows 10 November Update from 2015. The lines we mentioned exist here too, but are ordered differently.
Then, press the Enter key to execute it and see the information you need.
The Version number tells you the build of Windows 10 you have installed. In the earlier example, the build number is 19044, which comes after 10.0. With this number, you can then make sense of the exact Windows 10 version you’re using, so continue reading.
Until November 2021, Microsoft kept updating Windows 10 and released two major feature updates each year. These feature updates have a specific version, a marketing name (like Creators Update or November 2021 Update), and come with new features, new apps, significant changes, and so on. As a result, Windows 10 has evolved a lot since it was first released in July 2015.
From November 2021 onwards, Microsoft is changing the Windows 10 release cadence to align with Windows 11, targeting annual feature updates in the second half of each year.

According to this page on Microsoft.com, the retirement date for Windows 10 is October 2025. This means that we shouldn’t expect to get a new Windows 10 version past 2023 at the latest, since that would imply the need to support this operating system past its October 2025 retirement date. However, these dates may change, and we’re keeping an eye on what Microsoft communicates in the future about its plans for Windows 10.
You can have one of the following editions of Windows 10 installed on your computer or device:
- Home - the most used edition of Windows 10. It is designed for home users and new devices sold in the retail space. It includes only consumer-oriented features, and it lacks business features like BitLocker encryption or virtualization.
- Pro - this version adds features for small business environments and power users, like BitLocker encryption.
- Enterprise - provides all the features of Windows 10 Pro, with additional features to assist network administrators and technology-oriented companies.
- Enterprise LTSC - the long-term servicing channel of Windows 10 Enterprise, released once every two or three years. It is supported with security updates for ten years after each version is released.
- Education - initially had the same features as Windows 10 Enterprise, and it was designed for academic organizations. Since Fall Creators Update, its feature set has been lowered.
- Pro Education - a special edition of Windows 10 for the educational sector. It includes a “Set Up School PCs” app that allows provisioning settings using a USB flash drive. It does not have Cortana, Microsoft Store suggestions, or Windows Spotlight.
- Pro for Workstations - this edition is designed for high-end hardware, intensive computing tasks, and the latest server processors and file systems.
- S - a feature-limited mode of Windows 10, designed for retail and education. Its most important limitation is that you cannot install desktop apps unless distributed through the Microsoft Store. Also, Microsoft Edge is enforced as the default web browser with Bing as its search engine. Windows 10 Home, Pro, and Pro Education can be run in S mode. Other editions cannot.
- N and KN - N versions are available only in Europe, while KN versions are available only in Korea, to comply with antitrust laws in those regions, where Microsoft has been found abusing its monopoly to hurt competing video and audio applications. These editions of Windows 10 remove Windows Media Player, Groove Music, and other multimedia features. N and KN can apply to all other editions of Windows. Therefore, you can have Windows 10 Home N, Windows 10 Pro N, and so on.
- IoT - this edition is designed for low-cost devices like Raspberry Pi and specialized machines, like robots, ATMs, POS terminals, barcode scanners, and so on. There are two editions of Windows 10 IoT: IoT Enterprise and IoT Core.

The OS Build number changes with the updates you install while using Windows 10. To help you understand, let’s take the following situation:
When Windows 10 October 2018 Update was released, it had version number 1809, and the OS build showed the value 17763.1. After the first update to Windows 10, the OS Build changed to 17763.55, while the version number remained the same. After the most recent update to Windows 10, launched in November 2021, the build number has become 19044.1348.
The OS build number changes with each update made by Microsoft to Windows 10. This information is helpful for troubleshooting purposes. For example, when you encounter a bug and talk to a tech support engineer, the OS Build is critical to understanding the exact version of Windows 10 you’re using and what updates are necessary to fix the problem. You can learn more about the evolution of Windows 10 build numbers from this Windows 10 release information.
This information only tells you whether Windows 10 uses the 32-bit or 64-bit register of the processor. Modern processors tend to be 64-bit, and their advantage is they can address and process a lot more data than 32-bit processors. So in most cases, Windows 10 should be 64-bit, which is a good thing.
