I believe Wise Folder Hider has a memory leak (the WiseFs64.sys driver)!
See the very end of this post on SuperUser.com: https://superuser.com/a/949246.
I have also experienced this issue personally, when Wise Folder Hider was installed my 16GB RAM was ~80% full at boot (Paged Pool of ~10GB).
Indeed, as described in the post, uninstalling Wise Folder Hider returned my RAM use to normal (~15% at boot).
I think this is a major bug.
Hope you can fix this, as I otherwise really like the product!
However, I don't think I'll be using it until this is resolved.
