It may take some time for these important updates to be available on your PC because Microsoft and the PC manufacturers are conducting extensive testing before they are fully deployed. Let's take a look at what's in the latest version, how to figure out which version to run, how to skip the waiting, and get the latest version if you do not already have it.

The version number "1903" indicates that you are using the May 2019 update. This is the latest version. If you see a lower version number, use an older version.
If you see a higher version number than 1903 on your system, you are probably running an instable Insider Preview version of Windows.
Upgrading to the Latest Version
When Microsoft provides the update for your PC, it automatically installs. However, Microsoft does not offer new Windows updates for all PCs at the same time. Instead, they are slowly being provided by Microsoft over time after both Microsoft and the various PC makers have verified that they are causing problems with different hardware configurations. If your PC does not receive the update, Microsoft is still not sure if it works on your hardware.
You can override this and still install the update. Finally, if you have problems, you can always get back your current version of Windows 10, if you do so within 10 days of the upgrade. There is some risk here, but you are still installing a stable operating system update.
To install the update anyway, go to Settings> Update & Security> Windows Update and click on the "Check for Updates" button. If a stable version of Windows 10 is available, Windows Update may be able to download and install it – even if it is not already installed on your PC. Look for the "Download and install now" link, which states that a "feature update" is available for your PC.
Download the Windows 10 page for upgrade. Click the "Update Now" button to download the Update Assistant tool and run the tool. Your PC will be upgraded to the latest version of Windows 10 – even if the update was not offered through Windows Update. The tool may still refuse to install the update if some issues need to be addressed first with the configuration of your PC. You can either wait or try to fix the problem yourself.
