Explorer Forgets View - Folders Bar

I like my explorer in the "classic style" with the Folders bar down the side and all files listed in "detail", but since the last couple of automatic Windows updates, it no longer starts up with the Folders bar, which I have to manually click every time, and shows all files in icon by default. Until today, if I click on View Detail, Windows remembered this for that particular folder, and over time all of my regularly visited folders would start up in detail, so the manual configuration was only minimal. Today, however, all files in all folder are back to icons as default, and Windows no longer remembers the detail setting when I revisit folders.
