Determining whether the Windows 10 Anniversary Update is
installed
How do you determine if the Windows 10 Anniversary Upate has been installed
on a system running Microsoft Windows 10? There are several methods that you
can use to ascertain whether the update has been installed.
Use winver to determine the installed version of Microsoft Windows
In the Cortana "Ask me anything" field, type winver and hit
Enter. If you see the version listed as Version 1607 or
later then the Anniversary Update has been installed.
The "16" is for "2016" and the "07" represents July, though the Anniversary
Update was released in August. The original version of Windows 10 was
"OS Build 20340" and the "November Update" version of Windows 10 was
"Version 1511 (OS Build 10576.29)". The "15" was for "2015" and the "11"
represents November of that year.
System tray layout
You can also tell if you have the Anniversary Update by looking at the
system tray, aka "notifications area" at the lower, right-hand corner of
the screen. The Action Center icon will appear to the right of the date and
time, as in the example below, if the Anniversary Update is installed. In
the example below there are four notifications for the Action Center.
Using systeminfo tool at a command prompt
You can also obtain a command prompt
and use the systeminfo command to determine whether the Windows 10
Anniversary Update was installed and the date and time the Anniversary Update
was installed. E.g., the example below is from the same system as used in the
examples for the two methods above - see
Determining the version of
Microsoft Windows from the command line for further information on
determining the version of Microsoft Windows from a command prompt.
C:\>systeminfo | findstr /R "^OS.Version Original.Install.Date"
OS Version: 10.0.14393 N/A Build 14393
Original Install Date: 9/21/2016, 9:39:53 PM
C:\>
In the output above, the operating system (OS) version is listed as
"10.0.14393 N/A Build 14393", though the graphical user interface (GUI) example
using winver shows "Version 1607 (OS Build 14393.187)". The output from both
the winver and systeminfo commands shows "Build 14393". The "Original Install
Date" shown above is not the date Microsoft Windows 10 was installed on the
system, but is, instead, the date that the Anniversary Update was installed.
