Recently, Microsoft released Windows Terminal, an app that allows you to open Command Prompt, PowerShell, and Linux Shell in a single place. But, you need to at least use Windows 10 version 18362.0 in order to use it. How to check the version as well as the OS build on Windows 10?
On Windows 10, OS Build is a line that shows the specific operating system build you are running. This line gives you some kind of a timeline of the minor build releases in between the major version number releases. A minor build release (which represented by OS Build) typically contains minor changes only. Microsoft will use Version instead of OS Build if they want to release a new build with major changes (i.e from version 1809 to version 1903 ).
To check the build version of Windows 10, you can go to the Settings window by clicking the gear on the start menu or simply press Windows+I keys on the keyboard. On the Settings window, navigate to System -> About. Once the About window opens, scroll down to the Windows specifications section.

As you can see in the screenshot above, there are four lines available here:
- Edition. This line tells you the Windows 10 edition installed on your system. As you know, there are about 4 editions of Windows 10: Home, Professional, Enterprise, and Education.
- Version. This line tells you the information on what Windows 10 version you are running. The number on this line is based on the date of the most recent large build release. At the time of writing, the latest large build release is 1903 (Read: How to Manually Update to the Latest Version of Windows 10).
- Installed on. Tells you the date you installed the latest Windows 10 version.
- OS Build. As briefly mentioned above, this line tells you the specific operating system build you are running. OS Build represents the minor build release. If, for instance, Microsoft releases a new build release with minor changes, they will use OS Build instead of Version.
