Alright, just downloaded WR AIO v. 3.9.4 and, again, in the Registry Backup component, which is v. 3.4.1, my preference settings were again returned to defaults. It would be nice if, when updating WR AIO to a new version, the RB settings were maintained. For one thing, as I keep more backups than the defaults, some of my registry backups get deleted if the "keep minimum number of backups" settings is reset to the default.
