There are so many free programs available for Windows on the internet, but they all may not work for your version of Windows as every program is designed to keep a particular version of Windows in mind. This is why it is a good idea to know which version and build of Windows operating system you have installed on your computer. There are many ways to find out this information in Windows 10. But here we are giving a simple method to show the Windows version and build number.
- Press the hotkey Win + R on your keyboard to open the Run dialog.
- In the Run dialog, type winver and press Enter.
- This will open the About Windows window displaying the Windows version and the build number in it. The following screenshot is taken in the Windows 10 Technical Preview version and shows version 6.4 along with the build number 9481.
If you are comfortable with using the old fashioned commands, then you can also open a command prompt window and type the command ver in it. In this case the build number is not shown separately, but is appended to the version number. For example, in the following picture it is showing version as 6.4.9481 implying version number 6.4 and the build number 9481.
Other than these two straightforward methods, you can also use some of the third party tools to get detailed information about your Windows version as well as other things about it. For example, the HWiNFO tool can give you extensive information about your computer including both the software and hardware installed.
