same issue here, it started 3 days ago right after eset detected a false positive (version 8.0.319.1)
if i restore right before eset is installed the issues are gone, though i wish i won't have to do that as i've reinstalled a lot of software/settings.
if it can be of any help to the dev team, it seems like the system cannot write/read anymore the shell\bags path in regedit, as by using "shellbagsview from nirsoft" i can see that the folder preference are not created/modified, and even if i import the registry settings from the system state before the issue appears, the settings become visible on shellbagsview, but if i open the folder and resize the icons or the window, the lastmodifieddate still remains the old one.
Uninstalling eset doesn't fix the issue, something gets corrupted.
Please let us know if there's a fix as soon as possible
