How can I force my Windows 10 laptop to update?

Windows Update tells Frank that Windows 10 is up to date, but he still needs to install a new version

Why does my HP Pavilion laptop tell me that Windows 10 is up to date, but at the same time tells me I'm running a version that's nearing the end of support, and recommends that I update to the most recent version? Frank

First, some background. Microsoft used to provide new versions of Windows every three or more years, and support them for 10 years. Examples included Windows XP and Windows 7. They didn't change unless Microsoft released a service pack update, such as Windows 7 SP1.
