Well...but I don't know which files will be updated when, and Windows 10 likes rebooting itself automatically to update files. On top of that, I'm not terribly worried about malware encrypting Windows, more like it encrypting my own data files, which change much more often than several times a year. Some malware gets delivered to my computer as a new file, and the code that it contains begins to execute as an admin user. Its attempts to mess around with C:\Windows is thwarted by block-level protection. Instead, it goes into C:\Users\Me and starts encrypting stuff (not block-level protected, because it's all constantly changing anyhow). So, it can't modify the Windows system files that I could just re-install anyhow, but it can modify the creative output on my disk that only exists in a month-old backup copy, or something. Given that scenario, I'm not sure how much help the ability to write-lock blocks would be.
