Today, we were troublshooting an issue where only folders would display in an explorer view, but they would only show “Last Modified” date – no folder names. You can right click the folder, and view the folder name, and you could add the column “filename” to the display – but the “Last Modified” date was the “default” column.

After some extensive googling, I came across a forum thread that referenced this registry key:
We backed up the “PropertySchema” branch, and then deleted the “CachedSchema” key. After killing explorer.exe, and relaunching it the problem was fixed.

We aren’t sure, but it seems most likely (due to the state of this machine) that this was caused by a virus.
