Joshua McKenzie commented on CASSANDRA-8390:
--------------------------------------------

The best current method I have is to use msinfo32 to check for file system 
drivers and to deduce from there.  I'll see if there's some way to query from 
user-space - 
[handle|https://technet.microsoft.com/en-us/sysinternals/bb896655.aspx] from 
sysinternals lets you run a standalone query for what has file handles open but 
running that manually isn't realistic as you'll miss transient handles and most 
of sysinternals stuff is implemented as kernel drivers, so if we find some 
route to get this same information we'll likely have to take a different route.

Excluding the Cassandra folder from Windows Defender is highly recommended but 
I can't speak to the rest of your environment w/regards to file system drivers.
