Go to the Start Menu and type “update”
Select “Check for updates”
If you cannot find this option, choose "Settings" and then "Update & Security"
Choose “Check online for updates from Microsoft Update” (see picture)
If you don’t see that option right away, sometime you need to click the “Check for Updates” button first
It may take some time to download everything. You can use the device as normal while it's working.
Once it finishes downloading, restart for the updates to apply.
