I just had to register to post my disappointment too:
I used Eset Smart Security for at least the last 5 years IIRC, and never had such massive (unfixable) problems since i used it on Win10.
Besides the folder settings not saving anymore, i also encountered other problems, where the Read/write policies for several folders got corrupted.
All this forced me to reinstall Win10 to get it fixed again.
Since then i tried another Security Suite, Bitdefender, but uninstalled that ###### after a few days again. Not using a security suite since then, besides Windows Defender.
I REALLY hope Eset gets their ###### up again to fix their Software for Win10. I mean it's over a month now, and i see no real fix by the dev team themselves.
