I don't want Windows Explorer to customize its detail columns automatically when the directory has images or audio files. I want the old-school look of just file name, size, type, date modified. I have to set this up manually every time. How can I lock this in for all directories once and for all?
Not sure if this is exactly what you are looking for but it is worth a shot. This should set all Explorer windows back to the old school style you want.
IN regedit navigate to the following key HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell
and then change the value for "FolderType" from whatever it is to "NotSpecified".
