I had a curious email from Microsoft recently which saying:
“Support for early versions of Windows 10 recently ended and PCs running these versions no longer receive security updates”.
This does not mean support for Windows 10 is ending, rather if your machine has not been regularly updating – maybe because you do not plug It into the Internet much – then it won’t automatically update in future. They then linked to the Microsoft page where you can download a free installer for the latest version of Windows 10: https://www.microsoft.com/en-us/software-download/windows10…
If you do not connect your machine to the web then don’t panic. All this means is that if you decide sometime in the future you want to get to the latest version of Windows 10 then you will have to manually download the installer and install it. If your machine is on the Internet then it is probably up to date because it is actually quite hard to stop Windows 10 from updating. You can do this with the Pro version of Windows but the Home version does not let you stop it from updating itself. For most people this is not a problem and it is definitely best to keep your machine up to date if it is on the Internet.
