I have this problem as well, but with NOD32 and Windows 10 pro x64. You are not alone. There are many people suffering from this issue since the past few days. hxxp://www.tenforums.com/general-discussion/17175-windows-10-folder-view-settings-desktop-icon-positions-not-saving.htmlHere's a large thread on another forum where people have the exact same problem. They also all seem to have ESET products installed coupled with W10. Let's hope ESET can push out a fix sometime soon.
