macOS – Disable Drop Shadows Around Windows and Menu Bar

OK just tested this in SL and it worked, icon was removed but spotlight was still working in Finder:

$ cd /System/Library/CoreServices/
$ sudo mv Search.bundle/ Search2.bundle/

Now restart SystemUIServer, the icon is gone, Spotlight still works. To get Spotlight icon back:

$ sudo mv Search2.bundle/ Search.bundle/

And restart SystemUIServer again...

According to the Simple Help discussion Overview: The OS X 10.5 (Leopard) Finder, the scope of the two view options commands is as follows:

• Always Open in xxx View: Applies only to that specific folder.
• Set as Default: Applies to all folders opened in that particular view, meaning that it sets the defaults for that view as opposed to the defaults for that folder. (In my original question, the answer is #1.)

Armed with this knowledge, my problem must stem from old .DS_Store files in some folders as to why in certain folders the text size deviates from my default 10 point default.

Deleting .DS_Store Recursively in Folders

My frustration and confusion from seeing folders open not using my defaults appears to have stemmed from old .DS_Store files from folders that I had copied over from an older machine. To resolve, I recursively deleted the folders as follows using Terminal:

cd ~/Folder with bad views
sudo find . -name ".DS_Store" -depth -exec rm {} \;

Kudos to the Adobe TechNote Removing .DS_Store files on Macintosh OS X? for providing this command to delete recursively.
