Microsoft changed how feature updates are released on Windows. While updates are still delivered via Windows Updates and other update options, updates on Windows 10 are not reflected in the operating system's name.
There is no Windows 10 Service Pack 1, or Windows 10.1, for instance, and Microsoft has no plans to change that.
This makes it a tad difficult to find out which version of Windows 10 is installed on a device.
Microsoft does have internal names for updates, the Anniversary Update for instance was released on August 2, 2016 and the April 2018 Update in, uh, April 2018. Those names are not added to the version of Windows 10 on the other hand.
Probably the best option to verify which version of Windows 10 is installed on a device is to use the winver command.
This launches a small About Windows program that lists information about the installed version of Windows. The program is also available in previous versions of the Windows operating system.
The program lists a version and build number, and both help you understand which version is installed.
Finding out can be useful in making sure that you got the most recent version for example.
The version uses a four digit code that refers to the year and month of release.
The OS Build number offers the same information as the version. It is a bit harder to decipher though as you cannot draw a direct link between the build and version.
The major builds of Windows 10 Stable are the following ones:
Note: The Anniversary Update is released in August 2016, but the version states 1607 meaning July 2016.
Note 2: The About Windows screen highlights the edition of Windows 10 as well. You find it listed in the first sentence after the copyright notice.
You may check winver to find out if you have installed the most recent Windows 10 feature updates on a computer. Knowing the version may also be useful to find out if a guide, tutorial or news article applies to the version of Windows that is installed on your computer.Advertisement
