If you've been putting off installing the Windows 10 October 2018 Update - for obvious reasons - avoiding it will soon become a lot harder in the coming weeks. After Microsoft announced that support is coming to an end, Windows 10 Mobile users had to give up on their phones.

That came just a few months after Microsoft discontinued Windows Phone 8.1, the final operating system sporting the Windows Phone name.
