To mitigate, I am running Debian as the host and jailing Windows 10 in a Virtual Machine, and have uninstalled SMB1.0 on the machine by going into > Programs and Features > Add or Remove Windows Components. I have also blocked port 445 (SMB) with ufw (On Debian)

    sudo ufw deny out to any port 445

Aswell as this I am not deferring updates in any way and dutifully patching. I've always hardened Windows in this way and I've never had issues with malware, and if I did, the impact would be minimal because I've compartmentalized my files in such a way that even the worst malware would only encrypt some of my files and not all of them.

I store all my critical files in an offline environment (sandbox) so the only files that are going to be encrypted are replaceable (non important) and disposable. For example, I wouldn't cry if my C.V got encrypted because a copy of it exists in about 50 locations either offline and online.

Unfortunately I need Windows because my colleagues like to send Windows-only .DOCX files which work best in MS Word, and I don't have a Google account, so I can't open them in Docs. This is a conscious decision to permaban Google from my life, but Windows is staying.
