Windows Defender has significantly Improved In Windows 10, however It does not prevent the majority of ransomware.

Agreed, I use windows defender in conjunction with Malwarebytes and common sense, never had an issue. In fact, I just bought a Malwarebytes premium key for my laptop because I have it for my desktop and it's well worth the few dollars I paid on shoppy.

Malwarebytes Is brilliant. I have It running on every system (7 In total).

Spoiler:

A while back, one of my test systems was Infected with an .exe hijacker which did exactly that- hijacked every executable file and rendered the lot useless. Every leading AV I tried (Kaspersky, Norton, Avast, Avira, ESET, Trend, McAfee etc) failed to detect the Infection, let alone remove It. Malwarebytes got rid of It within 5 minutes.
