There are two ways to get the creators update. The first is to wait for Microsoft to push the update out to your device automatically. This can take up to a few weeks, and you may not receive the update immediately after it’s released.
The second way to get the creators update is by manually checking for updates in the Settings app. To do this, go to Settings > Update & security > Windows Update and check for new updates. If an update is available, it will be downloaded and installed automatically.
