This is essentially the same technique users of Windows XP use to keep using it securely despite the fact it is not supported any longer by Microsoft, and it's simple enough most people can do it. With Windows 10 updates basically guaranteed to bork something, including possibly your entire machine, and with the inability to cherry pick which updates you want, there is another option: disable updates completely. This of course leaves security holes which can possibly lead to attacks. There are two ways to throw enough barriers over these holes as to essential render them sealed. The first is something we should all be doing anyway, and that is using an extremely restricted standard user account as our everyday account and not one with administrator privileges. The second is to use an isolated virtual machine and a Linux based OS to access the internet, emails, and chats, further secured with extensions such as NoScript and keeping all plugins on ask to activate, while using your Windows OS for games and known trusted applications.
Think about it, an NAS can be used to transfer files over if need be, printers are connected to routers these days, most programs have a Linux based version (Firefox, Chrome, OpenOffice, LibreOffice, etc), Linux distros such as Ubuntu have matured very nicely and have a much more simple UI, monitors have the space and resolution to use your main OS and virtual machine side by side, computers from the last 5 years easily have enough power and memory to spare for a VM, and most of your data breaches occur by the site being hacked or a malware laced drive by download instead of a keylogger or other malware.
