In news unlikely to surprise anybody, Windows 10 is rapidly approaching its October 14 expiration date. That doesn't mean you'll be waking up on October 15 to a computer that no longer functions, but it does mean you'll miss out on Microsoft's technical support, feature updates, and security patches.
You can probably make do with the former, but the latter will leave you, your data, your hardware, and your system integrity completely exposed to every ne'er-do-well netizen with a willingness to exploit legacy machines (of which, there are a lot).
