the GetWindowsVersion() method is used to obtain the version of the Windows 10 operating system. The Major, Minor, Build, and Revision properties of the Environment.OSVersion.Version property are used to obtain the version information, which is then used to create a new Version instance. The resulting Version instance is then returned from the method and printed to the console.

The resulting output is a message indicating the version of the Windows 10 operating system. Note that the output format may differ depending on the version of the operating system, and that you should use appropriate error handling and validation when working with system-level functions.
