you are behind in feature updates. support is ending for the particular windows version you have. it is generally important to always have security updates.

i know that, at least at first, microsoft was not sending the features updates to certain computers if the computers may not have been capable of handling them (old/unsupported hardware, etc). i don't know if there are devices which are ultimately never offered the updates. try searching your computer model and windows 10 1703.
