According to Settings >> System >> About I have currently:

• Windows 10 Pro
• Version: 1703
• OS Build: 15063.850
• System type:x64-based processor

Which of these updates do I have to install? Windows Update Catalog

I've tried to install all files classified as "Updates" but always get an error "The update is not applicable to your computer"

So what update do I have install to get the "Feature upgrade version 1709"?
